First of all, running through the enemies is a great idea and when it works, it works. When the basic enemies spawn in a straight line with just small pockets of other enemies, and you can run through them while just pressing shield, it's really nice.
I see the vision, and I really like the idea! But the character movement feel jerky and like you can hardly control them (which would be fine, if running into enemies didnt require some amount of precision to pull of) and the fact that the sword swings slowly and clunkily takes this down from a satisfying experience.
This game really suffers from not communicating well to the player. I still have no clue what any of the upgrades I picked did, I don't know what ends any of the floors (i presume one of the bosses), and the fact that dying and moving to floor 2 have the exact same animation also doesn't help the overall impression.
It took me a few tries to get it, and I had to really read the itch.io page to know what the game wants me to do. But I had fun playing the game, despite my criticisms - again, when you get to run through those skeletons in a row and watch your power go up, while only pressing the shield a few times, it's really satisfying, the combat is essentially inoffensive, the graphics and animations are cute and the enviroments are basic fantasy land.
