Great job on the art, sound, and music! I see some megaman inspiration here not just in the powers but also in the animation that plays when you get hit. The sword dash feels really nice.
I think you could make the jump feel less floaty if you made the fall speed of the jump faster. The rocket felt less fun than the previous two weapons. I think some checkpoints should have been added, I felt it was pretty hard to get past some sections. I kept dying and starting over from the beginning was a little bit of a bummer.
Overall though, ya'll did a great job!! I read in your submission that it's the team's first experience with game development... that is amazing considering the quality here. Hope y'all keep making games!
