A really solid little platformer! The "striped" style is pretty cool. Slimes have never seemed so terrifying though. :D
I really wish the sword had a bigger hitbox as I ended up writing it off as completely useless because the slimes have so much combat capability than our poor knight. I ended up avoiding them, or juking them into spikes as that seemed to be more viable than hitting them with the dang sword. Kudos to you for making that possible!
I appreciated the coyote time as it saved me on many occasions. The movement mechanics in general felt really good. When it comes to platformers nothing could be more important!
Maybe this was just me having a braindead moment, but after I got the first key half I couldn't tell where to go next and ended up going back a couple of times thinking I had to return it to "home". I died about three times before realizing I could go right.
That last level meanwhile was absolutely brutal, being so long and with no checkpoints. By the end it was starting to feel like "getting over it with MaxScore". The little twist ending was cute though!
