A unique combination of puzzle and tower defense. The idea of the game is there are hordes attacking multiple points on a map and you can usually only save one or two before you either die or run out of time. The game then rewinds and you team up with your previous self to save everyone and eliminate the hordes. The puzzles are easy to start but ramp up considerably. Game seems to be about 10-12 hours in length for single player campaign but I have not yet played the multiplayer. All in all quite a fun indie game with a unique concept.

Edit: There are also 41 challenge missions that are quite fun. Some change up your strategy completely, while others just require maximizing your efficiency.
