Grass Tower Defense
\nThe game is about a developer who tries every day to stop enemies (black cats inspired by GitHub’s mascot Mona) from overwhelming the field.
\nGrass Tower Defense is a strategic tower defense game inspired by GitHub’s contribution graph, which is famous for its grid of green squares. In South Korea, this graph is affectionately known as the “grass field” (잔디밭), and developers often say they “plant grass” (잔디를 심는다) every day they contribute code. This charming metaphor represents daily progress as if nurturing a lawn, where each contribution adds a fresh patch of green grass.
\nGame Introduction This is a tower defense game inspired by GitHub’s commit graph. Build towers and defend against monsters.
\nAbout\nGame for the js13kGames competition 2025. (Theme for this year is Black Cat.)\nCharacters and images are made of Aseprite.\nThe sound effects were made of ZzFX.\nThe BGM were made of ZzFXM.

The mechanic of only being able to add towers to the current day was neat. I do wish the whole thing had been faster though, each day took quite a long time.

At first, it felt too short to really feel like a day, so I set the current time.
\nMaybe my sense of time got a bit dull from working on the same screen too much. Haha, thanks for the feedback!

I liked how you can regain energy to work more by drinking coffee and eating a chocolate bar. I just wish it were easier to see the entire screen at once, especially on a small-screen laptop.

\nThank you for the feedback!
\nI’ll pay more attention to this in future jams.

First, I can’t know how much effort you’ve put on the game, so don’t mind me if I get cliché or repeat ideas you simply didn’t get the time (or kb) to finish. Second, great you have finished and shipped a complete game!
\nI enjoy incremental games and this one was yet another interesting concept. I liked the mix of tower defense, the theme mixed with the work, and the economy between caffeine and money :)
\nI still didn’t decide if it was a bug or not, but after losing the game, you got to keep only part of your upgrades, but also you kept the previous level together with the octocats keeping their speed. Because we didn’t keep some of the upgrades I leaned on it being a bug, but keeping the velocity of caffeine charging activity allowed me to go further on the subsequent runs, so maybe it was intentional.
\nI liked the work on the audio, the towers shooting gave it a nice movement, but at some point the amount of towers just made me turn the sfx off hehe. In any case it was great that you had separated buttons for muting the music and the sfx.
\nThe only mechanic that I wished the game didn’t have or worked differently was the caffeine one. I kinda forgot about it over and over, always got a bit mad the activity stopped and it was a chore to keep it high, without any interesting decision towards it.

\nI like the concept and layout and you’ve put together a good game
\nThe music is great
\nI guess it would work better on desktop as there is so much clicking required, maybe allowing the %1 work button to be held rather than clicking 100 times would be good? I didn’t play for long enough, I’m afraid, to see if it went up to 5% or something
