I find the visuals of the game very succesful and charming, UI, DC portion, platforming portion, i especially like the character sprites. I also enjoyed the humourous and clever wiriting of the dialogues. My only major issue with the game is that i personally don't think dc/2d platformer fusion is a very good idea i mean it could be a good idea for the fusion maybe but not in combat. Maybe it could be like Zelda 2. The overworld is 2d sideview and when you enter dungeons the camera switches to first person view or something like that . Combat didn't click with me for couple of reasons:
A: It's repetitive. You play in the same area back to back a couple of times, same enemies, same layout and on top of that i think enemy encounters are too frequent. Also i learned it before reading your description page that all enemies respawn when you load the game :)
B: There's no reward for getting into combat. There's no character development and equipment system in the game so you don't gain experience or get loot from combat, you just get some potions which will heal you at the end of the combat. So the way i see it, the enemies just serve as roadblocks. It could still be fine for me if encounters weren't this frequent and combat didn't take so long+repetitive
C: This can be explained with the abstraction principle in games but i personally find it incoherent. Not sure it can be really considered as a flaw. Maybe it's just a personal thing but we encounter with one enemy in the dungeon, why do we have to fight against whole gang of enemies in 2d mode? I think then they should be represented as a group of multiple enemies in the dungeon or we do 1vs1 combat in 2d mode
These are the notes i took about your game. I played it around 1 hour and then had to abandon it bcs of the reasons i stated above. I think if you fix a few things here and there, it can become a very fun dungeon crawler game, the base of the game looks pretty solid and it looks very nice/polished
