I really like the concept but please add support for wasd. Using arrow keys is actually torture.
Control a blob while avoiding the bullet hell. Other blobs appear randomly. Touch one of these and it'll stick to you, granting more points per second at the cost of expanding your hitbox. If any of your blobs are hit, it's game over.
Arrow keys, WASD, Gamepad D-Pad: move your blob(s).
Ctrl: switch between light and dark background.
