Hi, thanks a lot for your tips! I agree about adding the enemy, but I’m waiting until my test is over because I want my teachers to be able to play through the whole game and evaluate everything. As for the sprites, I think keeping a bit of transparency gives the game a unique style, but apart from that, your advice really helped — thanks again! Oh, and about the bug when changing the screen size, I’m not sure how to fix it since I built the game for a fixed resolution on itch.io.
