Cool game! I think the concept of a petri dish and biology works well with the theme, and the art and the sound is work really well together. The one improvement I can think of is with the nematode. There would be some runs where I would die about 15 seconds into playing due to the nematode instakilling without any warning.. I feel like the nematode should be much slower than it is currently, and there should be some about indicator about the player's proximity to the nematode. But overall, great job!
