Very nice aesthetic ! Music and choice of colors really gives a nice touch. Too bad there are no bullet sound, as it is the only "ambiance" thing missing.
Overall, the game is good, but lack some polish: the enemy behave strangly sometimes, they don't shoot where they are looking, no end goal.
I think the enemy may have too many HP: it seems that my weapon is doing almost no damage. It may have been better to have more enemies with less health in my opinion.
Great entry nonetheless
