Super fun! The gameplay is great! I really like the skeleton enemies, they're adorable and their bones make for great attacks to dodge. My record is wave 29, 5:10.
The whole design of the game is great, everything is super appealing to look at. Also shout out to the programmer- I can't fathom coding a game like this.
The voice acting is great too, the sounds are awesome.
(I wonder how you could add progression to a game like this? Maybe you use the coins you get during the game to unlock new skills or costumes? You could add a skill that happens when you click the key the knight is already on - like a whirlwind attack. And maybe the shift key could do something too- like if you hold shift and press a key you throw a projectile towards that spot.)
Great concept, great execution!
