Seeing the aesthetic and the gun with one bullet got me a chuckle, but there isn't much to the game to give it praise or critique. I didn't find it hard though, especially since there isn't a goal, just hit the enemy for a high score.
Ye my original idea for the game was way to big and after i could do that i made a new game(The one you played) in like 5 days(I was procrastinating and lazy) so now there basically isnt a game everything was thrown together before the deadline
