Hello, thank you for taking time to check out my game, and thank you for the very usefull feedback, yes i haven't even thought about the UI scaling aspect of my games, and yeah, a sense of progression would be a good indicator since the player have no way of knowing how far they have progressed from the player's perspective, and the enemies healthbar could be an interesting addition, and a highscore would certainly make the game more fun, thank you for the feedback! I have so much to improve from. I will make sure to check out your game!
