Neat idea. You need a button to get out of the controls page. I had to reload the website just to exit out of there and restart the game. The music is loud, you'll want to turn that down some. Overall pretty alright. Would be cool to see some shakeups to this like the enemies not only going straight across but more of a wave pattern that isn't the same each time it cuts through the screen. Think the Medusa heads in Castlevania games). Maybe different enemies moving in different patterns instead of the same sideways movement to get the player to think more of how to get through? Just some thoughts.
