The art style was very well done and the animations were solid. The enemies were designed very well and so was the main character. I really liked the menu design as well as the sound design of the game. The sound design fit the theme of the game and was a good high quality. I also enjoyed the effects of when a sprite is destroyed.
There were minor issues that I personally had with the game such as not having any recorded score; leading to not having much motivation to play the game for long. Another very minor issue that could be fixed with some polishing is that the enemy hit-boxes are noticeably bigger than the sprites themselves. I also found that the enemies spawn a little too quick, which means you die in quite unfair ways.
Besides the small issues, a solid game submission.
