The gameplay was pretty intense, fun, and well-executed, and the pixel art was pretty good! I do think you should have chosen a more fitting background (why is he in space lol), but other than that, good job!
the background was kinda a later addition- i initially made a "lost temple" tileset, but then i couldn't find any reason why a courier would be in a temple. so i kinda scrambled with the "world building".
I drew and animated the courier from 3 Second Delivery, for practice. I can't show you the animation cuz it goes over itch.io's 3 mb limit but I can show you a frame! You seem pretty cool. have a discord?
