I’m not thinking much of that but eventually my plan is to have things like e.g. burst combos, possibly add some dynamics (like the pop pushes the surrounding numbers a bit), add bonuses (like recovering one life, strengthening the central attraction that keeps the particles from leaving the circle and so on), an anticipation of what the next particle will be, and so on. It’s inspired by Tetris and Puzzle Bobble, and I’d like it to have a similar arcade-y feel.
