I quite enjoyed this game. The story was interesting, the main character was a pretty fungi, and the art + sound effects created nice atmosphere. Also it was cool that some enemies were not hostile, it felt like the virus/fungi was just wanting to exist at times and wasn't necessarily a threat.
Unfortunately I didn't finish the game, I think it's mainly due to the lack of checkpoints, because the difficulty itself felt pretty much fair and adequate. But because there were so few checkpoints at some point when I died in some silly way, and had to run through quite a big portion of the level, it just became frustrating. Also the control scheme was quite weird, but I actually got used to it after a while. All in all, a solid entry, good job!
