That was quite fun! The synergies was what made this interesting to play, but you seem to have noticed that already.
Some nitpicks: You have to replay the tutorial if you lose. That's acceptable the first time, but I would have given up if I had to do it again. The dialogue comes off as a bit filler, and I would rather have that time spent on polish instead of the dialogue system. The games does lack a bit of just that, polish. UI is a touch janky, unskippable tutorial, some actions like progressing to the next round is a bit unclear. So it might have been worth to cut a boss to have time for just polishing the heck out of this.
Absolute love the art though, and the synergies really tickled my brain in a nice way. Great work!
