Really great entry! I love the idea of having the autotrophs, heterotrophs, and decomposers split into their own sections, and its a super creative take on the theme. The game felt very well-paced to me, with lots of fun character interaction, as well as platforming challenges and exploration. At one point, I encountered an audio bug where the footstep sound kept repeating after walking into a room, and it never stopped, which was a little annoying, but it was only during the last few minutes so it wasn't too bad.
Overall, really well made, great job!
