Great comment, thanks for your feedback.
I have been working on some animations/ improvements to the UX to make it a little bit more clear how the aura system works. It's a stack, but once you get more than 3 auras in there, the game adds random auras that you've already learned to the bottom, so you never run out. There are already a couple additions to the game that I'm working on - a new actor, and an environmental hazard - and also a routine that randomizes the terrain. I'll try to put out another version close to or shortly after the conclusion of the jam!
(Also, in the jam version, I think the gator is too fast. It will be slower.)
