Concept being plain and simple but sparks so much charm! Sound effects are crunchy and satisfying to hear! Gameplay awfully cute and reminds me of those early 2000's Breakout games I used to see and play quite a few in my youth days. I also really dig the idea of the floor also being an obstacle as you juggle with projectiles to pass the level and survive along whilst keeping high score. Very reminiscent of Sonic 3's Carnival Night Zone boss where drills slowly destroy the floor.
I think you could also add more points and scoring events if the main robot will be able to survive level without losing lives, hitting multiple balls at the same time or not missing single star points. Otherwise there's not many Breakout or ball breaking games out there as this theme / category of game feels very left out. If fancy this project can be pushed towards Steam page or so I'd feel fancy to support since it is a quaint little project, also add nips!
