This is impressive for a jam game! The unit select screen is a bit daunting at first due to so much stuff to choose.
The characters are easy to discern between them, although the monsters are hard to check which is which. It would be nice to have a way to highlight the selected unit and perhaps a better way to see who has their ability fully charged.
The sounds and music are alright.
The tutorial is pretty good! Glad you put it there or else I'd be so lost. I mean I couldn't finish one Monster Incursion game, but I tried! Also, I guess you already saw this but the units used counter goes beyond 15 if you try to extend it after reaching the limit. Doesn't affect anything though!
Congrats on the incredible amount of content!
