You got a pretty solid game here. It was a little bit confusing at first, but once I read the how to play, I got it immediately. I like that you tried to go for a simple polished game rather then something super high scope. The gameplay does need work though I feel like you could've done a bit more with what you had like maybe you need to "reload" your fireballs or enemies killed to boss. The AI also seemed to simple that I could just hide from above stack and then wipe them out. I feel like if you had done something like Q to shoot left E to shoot right, W to jump, and A & D to move side to side in the main level that'd help with giving instructions to the player. Overall good job!
