Funny how every comment is crying about the controls, I liked them :P


Thanks! Finally someone on my side.


Great game, was simple to play and quite fun too. The IJKL movement setup was out of the ordinary, but wasn't anything too weird. I enjoyed it, a good solid entry :)


Thanks! Yes, the game is very simple. I personally like IJKL but I might be the only one :)


Giving my right hand a workout with those controls :\

Simple game with good execution.


Probably the weirdist control setup I've seen this jam. but it actually added to the gameplay a bit for me as I had to cross my hands to shoot xD. I liked the similicity and overall gameplay, but it could use a short tutorial explaining what to do, as I had to figure that bit out on the fly. Other than that a solid entry. Well done!


Thanks for the feed-back and for playing my game! For me the controls are natural but I guess I'm just weird :)


Wow! I rarely see a game made purely in HTML and JS so I feel this is quite impressive in and of itself.

I like the detail on how the cells get converted into virus cells upon contact (I also hate it because that's when I usually lose)

Although it took me a while to realize that you lose the game if a virus cell reaches the bottom, so I was confused for some time wondering why I seemed to be losing randomly.

Thanks for making this game!


Happy to get some feed-back! It was perhaps unclear that all the viruses had to be shot down before reaching the bottom of the screen. BTW: A virus is not a cell :)

If you like to know more about Javascript game programming you can check out this excellent tutorial:


Props on not using Unity like the rest of us plebs. At first I hated the controls, but then I loved them once I started pulling off some sick moves. Not very satisfying when you hit a cell that wasn't even on the screen though.


Thanks for playing and testing my game! Sorry for any cells that shouldn't be there.
