Solid game, I liked the combination of using WASD and arrow keys for movement and attacking respectively, though a nitpick I have is that using Space for jump would've felt a lot more natural. I also didn't understand why I kept dying in 1 hit, cause I noticed 3 heart icons whenever starting, so I assumed I had 3 HP, which doesn't seem to be the case. Based on the description, I can see how it relates to the theme, though it feels like a majority of the time is spent climbing the tower, so it doesn't feel like it fits while playing the game.
Overall though, this was pretty enjoyable, I liked the combat the most. Great job!
