It was really nice that you were able to add a tutorial section in, especially since there are some issues with movement in this game. I found that I could not move at all at the beginning of the tutorial and the first wave, but if I kept trying, eventually the character would start to move. When it works, I think the movement is pretty nice, as I was able to dodge and weave through enemies in later waves.
The number of enemies in each wave is more of less appropriate, but it's very easy to end up getting swarmed. It was also hard to tell what was happening whenever I was hit. At first I thought I was being instructed on how to avoid being hit again, but now I think you're inflicted with some sort of curse each time? That's a nice concept but it needs to be more clear.
Overall, I did find this game very fun. The different enemy types keep things engaging and the sound of your character's footsteps is oddly satisfying. Good job!
