Merge Rain: Number Rain Puzzle

On rainy number days, one brush is all you need.

Number drops - 1s, 2s and 4s - fall from the sky without end.
Swipe your finger to draw a line, and a platform appears for a moment.
Roll and bounce the drops into the jar, and merge equal numbers to double them.
If the jar overflows, it's game over. Survive 10 minutes to clear the run!

What kind of game is this?
- A physics puzzle played with a single line: ink is scarce, spend it wisely
- Doubling merges: 8, 64, 1024... the numbers never stop growing
- Roguelike augments: every new number lets you pick 1 of 3; pick again to level up
- Tap the cotton candy within a second to earn a powerful relic
- Gold stays after every run: upgrade traits and try again (ball size, ink, auto-magnet...)
- Every run builds differently; finish 10 minutes for a clear bonus

You'll like it if you enjoy
- Physics merge puzzles and casual roguelikes
- A 10-minute run that fits perfectly into a commute
- Warm, cozy, hand-drawn vibes
