-Beautiful graphics with nice level design and a potentially great game.
-Sounds are good.
-The music feels friendly and well done... although as a personal opinion I'd like it to be less perfectly safe. It's a level 1, but you're facing skeletons and man-eating plants, after all. If you can, add a bit more personality to it, so that whenever a player hears it again they will immediately think about this game/level.
-Controls are nice and the character is fun to move around with her diverse moveset. However, movement (especially landing, rolling and attacking) is not fluid at all and it feels heavier than a dark souls game. It didn't bother me much at first, but as the game progressed it got really annoying.
-Some of the tutorial letters at the beginning are a bit hard to see. because they float slightly off camera. They CAN be read, but I recommend fixing it.
-Overall this game felt me of a mix between Celeste and Dark Souls, which is a daring and brilliant idea... but I think your game would greatly benefit from a faster combat and jumping. Less delay between actions will make the player feel less frustrated when he dies and will make the game faster in many ways. Games like Celeste or Super Meat Boy have you die thousands of times, but because you're immediately trying again and they require all your focus you don't mind that much.
Oh, and don't let the criticism discourage you, I'm pretty sure you have all the ingredients for a big hit and definitely it's a game I'd buy. But make it more fluid and immediate!
