From a combat design perspective, I am impressed! It's not often that you see such a well-thought-out strategy game in a game jam, but here we are! Gameplay took a little getting used to, but once I got the hang of it I could tell there was a lot of depth. The bosses really don't let up after the first one either!
The colors were a bit harsh, but I managed to enjoy the game nonetheless.
I checked the tutorial before jumping in, and while that helped, it still took a while for me to properly learn what was happening. In fact, at first I missed the whole point of the game, that whichever skill is on the edge is the one that gets used! I thought it was more of a Slay The Spire kind of card-based game.
Given the complexity that you achieved in such a short time frame, I think your tutorial was as good as it could have been. The next step would have been if the tutorial walked you through a fight and explained how everything works in real time, but like I said, it's a game jam game, so I think you're fine here.
Overall I like the game! Great systems and combat design. I liked the worldbuilding aspects of the game as well.
