its mechanics are confusing and unexplained, to really enjoy this game you need to go in knowing how to control the "screen" and what the boulders can do to it. not mentioning other possible mechanics.
otherwise this game is a good little game jam time waster that makes late-night energy-drink-infused me cry play the game get stuck cry leave come back cry without playing the game leave come back play the game cry and pass out. I don't know if this is the games fault or my own personal problem but either way its still good.
