Great job finishing the jam! This is actually the first 3d game I've played in this jam, so good on you for tackling an extra dimension! I think this is a really cool idea for a game. I enjoyed trying to be efficient in how I managed my parasites while trying to grow as quickly as possible. Having skills to level up is an impressive feat as well.
A few points of constructive criticism: some of the UI was confusing and required trial and error to figure out. My first time I played (and lost) I didn't understand why there were two progress bars on the page for an infected, and some of the toggle button behavior didn't seem to work right on the skills page. One thing I'm learning is communicating to the player the things that you as a developer take for granted because you're the one that built them. Things like having people playtest your game, and really trying to think through what a first-time player will experience and understand can help to make a game more accessible.
Overall though, great job, especially for your first time in this jam! Hope to see you again in the next one!
