Thanks!!! It's indeed true that the sprites only use two colors. Initially, the sprites had more colors, but because they're only 8x8, it wasn't looking very well. As I didn't have much more time left and I really needed to focus on coding, I decided to make them simpler, which did not end well, it became easier to mistake one enemy for another. What I realized tho, is that it doesn't matter ahahah, just dodge the bullets and you'll be fine. I'm joking a bit, but you are right! Thank's for the review!
