Unfortunately there is a bug in the "a helping friend" level where the 'friend' spawns too close to the ground, which causes an endless loop of him falling to his death. This makes the level progression impossible (It's the second last level). We discovered this very shortly after the deadline, so we couldn't submit a fix since the contest was closed. We have this fixed in the latest build. If you want to play the game to completion you must avoid looking at the floor directly below where the friend spawns. Sorry!
