HTML5 and JavaScript Game Development Competition in just 13 kB

Space block invaders

This is my third entry for JS13k this year.

It’s more of a tech demo than a real game. It started as an experiment to see how much content of a Minecraft like clone could be done in 13kB. When I was done with the engine I started to play around with some small gameplay fitting the space theme and since I have spent some time on this I figured I could submit it anyway.

Normal FPS controls:

Move around with WASD
Jump with space.
Use the mouse to look around and the left mouse button to shoot at the invaders (or destroy the world yourself).

There is no real goal apart from survive.

It works best in Chrome but all major browsers are supported.

Jumping up trough trees is intended and not a bug.

Each game play has a randomised world generated during startup.

It’s a bit memory hungry and requires a good GPU to play but I have tried to optimise as much as possible.

Feedback from the experts

Christer Kaitila: What an amazing engine! I like how you have nice lighting in there as well, dark regions and ao in the creases and cast shadows, and I really love shooting holes in the trees! amazing work, it ran super silky smooth and worked perfectly abd fast. This could be the beginning of a really cool game engine!! I look forward to seeing it evolve post-compo! great job
