Love this pixel dungeon crawler style! I do have some feedback about the store page: all of the screenshots look almost identical, which I appreciate is kinda inevitable because of the game's visual style, but maybe trying to get a couple of different scenes interspersed between the walls-and-monster shots would go a long way toward capturing people's attention. Also, the trailer is similarly repetitive, so could possibly be shorter to avoid repeating too many similar scenes, as it makes the game look more boring - and I'm sure it's not! The music is also oddly cheerful, despite the game having more dark visuals. Perhaps some more tense/battle style music would be better (I'm a composer and can help with this if needed).
That being said, don't be discouraged, as I like these kinds of games, and it looks nice!
