Very promising! Visuals are awesome (especially graphic design. some enemies are uninteresting)
- balance is bad. For me (on normal) it was almost flawless up to the final fights where the death felt random and unfair. First levels were such a slug that I wouldn't restart. Ideally, first levels should contain a potential for all skill levels to shine! The minimalistic design leaves a little room for different strats, with such an open upgrade system it would be very hard to allow variety of builds to be equally effective.
- More of a personal one: I feel like 6 abilities in one hero for an hour of play became stale. You just repeat one attack pattern, then upgrade 3 essential attacks forever. I think its enemies. They need much more variety. Maybe force to switch abilities from time to time. (like durability, but something less irritating) And present more focused challenges in each zone, so that you need to tweak the build in anticipation. (Easy grunts shouldn't be at the latter part and so on..). Throughout the whole run I was thinking of hero party with 2-3 abilities for each one, but it's a pretty different game, sorry.
-A more subtle point: waves and recharge times as it is make waiting at the last enemy for a few turns an optimal play. It isn't fun. Defeating everyone in one turn is much more fun! Maybe endorse it? (I didn't understood combos. Make a DEMON FORM at 3rd combo or smth.)
-Coins. why are they lying at the battlefield?
Thanks, bye!
