The movement + shooting went very well. I do wish the game was a bit faster to better give a fast-paced feeling but this works well too as it keeps the player on his toes. Its nice that you focused on having one good working weapon as opposed to multiple weapons but not very well working! The enemy variety keeps things interesting as well, I do think some sort of multipliers/powers or even changes to the environment would work very well. The game balance also felt easy to start (thats good) but takes skill to reach a good high score! Congrats on the submission :D
