Scroll Happy Run

Scroll Happy Run starts you as one small figure rolling down a track, and the trick is that you are not meant to stay one. Other figures stand along the path waiting to be picked up, and each one you collect folds into the wheel and makes it wider.

Size is what gets you over the gaps, because a wide wheel bridges a hole a thin one drops straight into. It also costs you: scraping past an obstacle shears figures off the sides, and they stay behind. So every stage is the same quiet argument - gather enough to cross what is ahead, and arrive with enough left over to be worth the coins.

How to play

Guide the rolling wheel left and right down the track, steering into the little figures standing along the way so they join you and the wheel grows. Width is what carries you over gaps, so collect before a long jump rather than after it. Obstacles strip figures off as you pass them, and the number you finish a stage with sets the coins you earn, which unlock new characters to roll as.

Controls

The mouse steers, and that is all there is. Move it to send the wheel left or right across the track; you do not control speed, only the line you take. A finger dragged across a touchscreen does the same, which is how the game plays on a phone held upright.
