Unichrome: A 1-Bit Unicorn Adventure (UP)

This can easily be done on the first level (not the prologue). Just follow the path, collecting all coins, until you reach a gap. Jump over it across to the right and collect all the coins there. Go back and jump down the gap. Go right past the checkpoint, jump over all the pillars, then walk through the door to complete the level.

If you fall you will be back at the checkpoint.
