The game was quite enjoyable. I like the idea, the art you chose was quite good (but you should credit it), but there is no sound or music in the game and it was very much needed.
The gameplay was great. It was fun trying to deal with the multiple different infections in time. but i feel like the scrolling with X and Z makes switching between different infections way too slow, and instead should have been maybe with numbers and icons at the top. I didn't really find any bugs except sometimes if you win at the last second the "You Lose" screen still pops up over the "You Win" screen after the full 20 seconds have passed.
all in all, a good game, and I feel like if you had more time the game would've turned out a lot better, good luck in the jam!
Important Note:
The download you have of the game actually contains the unity project and the source code with the build. You should maybe delete these and just keep the build in the folder and re-upload the game download. It's safer for your game (someone could use your project as their own), plus it'll lower the size of the download. Don't do that right now though, you can't change the jam submission before the results are out.
