Very atmospheric, but a bit monotone.
I like the art, art direction, and music very much, the sound affects don't stand out, but aren't bad either.
Good variety of enemies, with unique behaviours.
Character movement was nice, and didn't get into the way of enjoying the game, but the attack is a different case. The windup is way too long on it. I don't know where to put the ability to attack up and down also, It comes out to slow to hit flying enemies, and you don't have a knockback or bounce when attacking down, so you take damage if you try to do that.
I was pretty directionless when exploring the map. You descend an elevator at the start, which is a nice start and makes you get ready to explore some unknown place. I was surprised to see another elevator right after that, and then another one. It takes the emphasis out of using a setpiece like that. Then I was pretty much lost traversing rooms, killed a boulder spitting wall creater, ended up back at the start, and got stuck in the ground.
I'd do want to play more of this, though
