Breja: Even by anime standards this is hideous. 
Was this made by AI? It looks AI-ish. 
  Now you're being rude. So this game was made entirely by one single person over a period of six years. Everything was hand-drawn. And it plays very, very well. I've been playing for six hours and have only explored a quarter of the game. Do not judge the game by how it looks, throw the CRT filter on it, which looks great - and go about your business. I've finished every single igavania since SOTN and this is the best one I've played since Bloodstained. It is an absolute must for fans of the genre, even it may not be the prettiest - the gameplay is here in spades. Now, there are some bugs that need to be ironed out in a 1.0 but they will be. So far, I like this more than Chronicles Of The Wolf and that was a tough bar to pass. Both are solo Spanish developers.
HunchBluntley: I expected one of the usual porn games, but it seems like this is closer to a Shantae game: horny anime-style HQ art (though more generic than the Shantae series', IMO) laid over a pixel-art metroidvania. Looks at least a bit more serious, though -- and that may or may not be a good thing. 
  This is a very serious game and you'll get destroyed on the nornal difficulty. After the prologue you start at level one and one bone from one skeleton will take massive amounts of damage. In fact, there's nothing even remotely pornographic about this game. It can be a very, very, painful experience though and on normal it turns Castlevania into Hollow Knight.
ReynardFox: Yeah the high-res portrait art ruins it, and it absolutely looks like it was AI generated. 
  Guy developed this game for six years by himself. He may have used it, but he also may not have used it. If he had the money to pay an artist for 75 tracks, he probably paid an artist for the portrait and CG art in the game as well. I've seen nothing that looked AI.  
 I have a gameplay video too for the normal mode so you can see exactly how tough it can be:
