Thorns are Roller Baller's only true hazard — the red serrated patches growing on otherwise friendly platforms. Touch one and you're back at your last checkpoint. Here's the full census, and the habits that make them stop mattering.
Where they grow
The course plants thorns in five spots, and every one of them follows the same design rule: thorns only appear on wide, comfortable platforms. The narrow islands — the genuinely hard jumps — are always clean. The game punishes complacency, not difficulty. The moment a platform feels safe enough to relax on is the exact moment to look down.
The three clearing techniques
- The hop: a short single jump from about one ball-width away clears every patch in the game. Don't double jump — the extra air time drifts you further than you think.
- The full-speed clear: at top speed, jump as the thorns pass under the front edge of your ball's shadow. You'll sail over with room to spare. This is the speedrun option.
- The full stop: new to a section? Just stop before the patch, reset your feet, and hop over from standstill. Slower, but a guaranteed clear beats a fast respawn.
The one that gets everyone
The patch on the finish island — after the last gap, before the rainbow flag — has ended more good runs than every other hazard combined. Your brain declares victory a half-second early. Treat the finish island as part of the course, not the celebration, and it will never touch you.
