Very fun autobattler.
I enjoyed the gacha aspect of rolling for new units, hoping for a higher rarity one or a dupe to upgrade my team.
The synergies are very nice (still haven't tried them all!) and those unique abilities in the higher rarity units have very cool animations (I love Calli's and Ina's)
I got Kaela in one of my rolls and it's a pity she was not implemented yet. XD
I hope you continue working on this gem of a game after the jam as there's a lot that can be done with so many characters and synergies, as well as more polish on the attack effects and such.
Oh yeah, I hope you also add some setting to make the screen larger (2x zoom for example) and volume controls.
Great game!
