I couldn't beat the whole game--I got stuck on level 5--and many of the levels I did beat I just jumped over all the enemies. I wasn't sure how to make use of the attack state without just taking damage myself. I did like the look of the game, but I didn't feel like it really made use of the assets in the most creative way (knights were knights, walls were walls, etc)
However, it is a game, and it feels finished, AND it has a level select screen. I really appreciate not having to start over every time I die. Good job!
