Fun experience! There are a lot of hitbox issues - the sword feels a little odd sometimes, it's not always clear when and how I can push boulders, that sort of thing. Also, it would be nice if after taking damage you gave the player a few frames of invincibility, just to give them a chance to save themselves if they get into a bad spot! A checkpoint/saving-loading system would also be very nice, but I understand why that wouldn't fit into the scope of a jam, haha!
Overall though, I had a lot of fun with this game. Great work!
