I'll be taking your ideas in the comments 🧡 I have some cool ideas for balls and squares! The game will have a lot better outlay (or smth else idk how to say it),animations and even more lore!
Squircle, an unlockable that has a badge:
When a square and a circle collide, theres a very low chance to a Squircle to create, its a shape that is a square with curved edges, the badge is How did you get here?
Proprieties: The squircle is a neutral form that doesnt attack but can be attacked, but it has the hp of a normal square and circle combined, so it could survive an attack.
