Yeah uhh, I'll definitely tweak it after the jam 😅 If it helps, you need to get a running start to get the full three-blocks-high jump you can do in this game. You can use your brake to help get closer to the wall without slamming into it, so you have more space to run.
And at the top, if you miss the jump right before the next tower, you can get a reset on your timer by jumping against the wall, since the signal extends half a block beyond the wall.
