Amazing, brilliant and refreshing take on balatrolikes! The combos you can do with abilities, charms and consumables seem endless. Loved it! Here’s my playthrough:
thank you for playing and for the feedback. this is still a proof of concept so a lot of the stuff is still unpolished. since you enjoy the game, it gives me confidence to continue with this prototype. if you would like anything added to the game please let me know as well :)
