PRIME DROP
PRIME DROP is a minimalist falling-number puzzle game where quick thinking meets the satisfying logic of prime factorization.
Numbers fall from the top of the screen, and your goal is to reduce them to 1 before they reach the bottom. Choose a prime number—2, 3, 5, 7, and more—to divide every matching circle on the board at once. Plan each move carefully, clear multiple numbers
simultaneously, build combos, and use your Blast ability when the pressure starts to rise.
The rules are simple, but each new stage introduces faster drops, larger numbers, and more complex factors. Recognizing patterns quickly is the key to surviving and achieving a high score.
Play with a keyboard or touchscreen, switch freely between Japanese and English, and see how far your number sense can take you.

Seems to easy to just spam the keys. Need limited presses or penalty for non-dividing presses.
Thanks for the feedback!
There is currently a penalty that reduces the combo meter when a press doesn’t divide any numbers, but I’ll consider adjusting it to make button spamming less effective.
