Wow, the battle system is really creative! I loved it! Pretty cool game, but I didn't get to see the ending (it has one?), after level 20 I got tired of going down lol. Still pretty fun anyway, though in my opinion you could ditch the dungeon crawler aspect because it felt more like a slog between battles than anything else. Maybe jumping from battle to battle with perphaps a little shop (perhaps to heal?) or something between 3 or 4 of the battles would've been better. And I think the lack of sfx and music really hurt an otherwise great entry.
Still, pretty creative! Hope you keep improving on it!
