Thank you for playing and the review!
Agree with you that game could be more polished but it was my very first completed game and I was focused and spent all time on implementing main mechanics: screen "glitch" - which took me couple of days to pass basic shader course, power-ups, difficulty testing and tweaking, and also having a couple game prototypes in my pockets I never before were creating an UI/menu, it also took a few days because Godot's tools for it felt very unintuitive for me.
