Since it isn't a fairly known game, I will try do make a brief presentation of it first. Pause Ahead is a flash game developed by Askiisoft, the indie team behind the best-known Katana ZERO. It's a puzzle-platformer with levels and a unique gimmick: when the game is paused, the protagonist enters a particular status in which he is invincible and in which he moves "by momentum" in the direction you were pressing before pausing.

Despite being a free game that lasts an hour, it is really nice, also thanks to the high general difficulty and the true ending. The soundtrack, composed by flashygoodness (peak) and Bill Kiley, features quite memorable melodies and is probably what stuck with me most about the game even years after my playthrough.
