The fear of prime numbers. Fear them all. Especially 13!

\n

Please read all instructions below. An introduction and tutorial were not added in game.

\n

Don’t let the timer get to 0 and avoid PRIME numbers in your score! If your score ever equals a PRIME number, bad things will happen to you, especially if it’s 13!

\n

If your score is doubles (11, 22) you will have a chance to grab a power up! Collect as many power ups as possible to aid you in higher levels.

\n

Advance to the next level by getting to 100 or more score.

\n

Beware of prime enemies. Contacting with them will deplete your score and freeze you for an instant, along with their shots as well.

\n

Place bombs to destroy enemies on contact.

\n

If your timer gets to 0 or you make contact with a large enemy (not the common prime enemies), you will die and will restart from level 1.

\n

Small hints around player: Bottom left green is what you should collect to get the next double, Bottom right red is what you should avoid for next prime, Top center white is your current score.

\n

The game is quite challenging, but is quite possible to win, especially collecting lots of powerups and playing with a gamepad! Hint/spoilers at very bottom of this page.

\n

Controls:

\n

Press R, Space, Enter or gamepad South button to begin

\n

Use arrow keys or wasd or gamepad left stick to move around and catch numbers.

\n

Left Shift or gamepad West button - Thrust

\n

R or gamepad East button - Place Bomb

\n

R, Space, Enter or gamepad South button to start over

\n

M or gamepad Select to mute/unmute music

\n

P to pause/unpause game

\n

Power Ups: U - Magnet Increase, T - Thruster Increase, S - Player Speed Increase, B - Bomb Increase

\n

Hint/Spoiler territory below

\n

The mid-boss at level 7 is quite hard, but defeating it is not necessary to advance to the next level.

\n

Highers levels do get quite hard but the final level is, you guessed it, 13. This involves a final boss fight; fortunately if you get this far dying respawns you at the final boss instead of making you restart the game.

Phew! After some 10-20 tries, I reached level 11 with score 1726. What a unique concept you have here, fits perfectly with this year’s theme! I had fun with this one. I think it has replay value since you slowly grasp what numbers to pick and how to avoid primes. Like, at first I was just picking even numbers but then, as I got a refresher on prime numbers, I started collecting odd numbers as well. And I did’t even focus on getting the doubles yet!

\n

After several attempts, the game seemed very very difficult, as even at levels 4-5 the numbers were really fast and scarce. Also, after starting the game again from start, a previously ongoing disability was still active. You guys didn’t have some global variables that were not cleaned up, now did you ;) After getting the habit of refreshing the browser after each game, the difficulty seemed properly challenging and the middle boss spiced things up nicely.

\n

Just a minor thing, but when having the fast moving “disability”, it was quite difficult to catch the numbers. Perhaps the game could be a bit more forgiving when collecting those (in player’s favor, not so eager to catch enemies :)? But yeah, I guess that was meant as a punishment so maybe it’s just me being clumsy :) Also, I did’t manage to use the power-ups when I happened to catch those, so it would be helpful if some help text would appear at the time that I could use them. But I guess time- and size constraints were limiting here :) But these things were really minor, didn’t spoil the game for me.

\n

The minimalistic graphics style fits the game spot on (at least I wasn’t missing anything fancier). Together with very good music and sounds, playing this is a rather meditative experience.

Thanks so much for the thorough and kind feedback! We may have used a few globals ;)

\n

You definitely found your stride in this game, just as we wanted. At first it is a bit difficult even with the helper numbers (green and red) below you and score right above you, but as you play a few more times you realize what you want to get and what you want to avoid, and even sometimes to get your score subtracted by purposely running into enemies.

\n

We really wanted a tutorial level to show and flesh out some of these concepts before the game really begins, but time and space constraints limited us here.

\n

The fast moving is supposed to be a punishment, like slow moving and reverse control.

\n

I’m not sure if we explained power ups correctly or at all, but each one builds some stats little by little so it’s not really noticeable except over time. You will eventually notice that you are faster, and that your boost button actually works for a time after you collect enough power ups, your magnet attract gets stronger, etc.

Interesting game! My best score was 815 on level 6. There are many different mechanics and systems to try to juggle in your head! I found the “don’t let your score equal a prime number” rule a little frustrating, so my strategy was to only go for even numbers. If I ever accidentally hit an odd number or hit a yellow number, then my goal was to patch my score and get back to an even number as quickly as possible. Personally, I’d recommend easing the player into the mechanics rather than enabling them all on level one. Impressive amount of content for a js13k entry! Nice music and sound effects too. Great job, congrats!

Thanks for the input, and solid score! I agree with your sentiment, it can be frustrating/overwhelming at first. I played long enough to where it became natural, but agree that we could have eased the player in. Thanks again.

The instructions are way too long.

\n

The game is kind of cute in graphics and music, but I found the mechanics of the prime numbers too complicated for the game to be fun. Basically what I did was catch only the even numbers to avoid the primes without having to think about the current total. Because while I’m playing, I’m not paying attention to the total.

I totally get it, that’s how I played at first! Solid strategy. The game does get easier and somewhat intuitive if you play it longer, but we don’t necessarily expect people to become experts at PRIMONUMEROPHOBIA!! Thanks for the feedback, and thanks for playing homie!

Neat idea, and the implementation of the theme isn’t subtle. :)

\n

Intuitively, the score should start high and decrease with pickups, so that the highest density of primes is towards the end of the level.

\n

Good idea with the hints, too. All in all, a solid little game, nice work!

Excellent idea to fit the theme!\nI loved the concept (I love maths, I don’t know if everybody would love to calculate prime numbers ^^)\nSound is nice, espacially the one used to compute score at the end of a level!

Glad you enjoyed it friend, we especially liked the SCORE tally as well! I just found a tone I liked in SoundBox, and monkeyed around a bit. Thanks for the input, and thanks for playing!!

Interesting game! A lot of concepts applied in the game… Also, very nice music, congratulations!

\n

I could reach level 13 but I couldn’t figure out how to beat the boss. By reading the game description, it seems I should drop bombs by hitting “R”, but it didn’t work, or I didn’t understand how :D

A fun little game, with a heavy maths element.

\n

Graphics are basic, but enough to get the concept

\n

Music and sounds are good

\n

Having the controls flip was fun, was that in relation to being a prime number?

\n

I felt the character moved a bit slow, and there was a lot to try to remember from the rules and instructions when playing.

managed to finish level yet having no idea what was going on, inverting controls was annoying but is a good way to make a bit challenge

This is clever, I quite enjoy this, it feels a bit like a lost BBC Micro or Arcade title. Good work on the new-feeling mechanic.
