Wow! This game is great! The rewind animation is fantastic and the concept of saving yourself is great! Haven't seen that mechanic anywhere else! The music fits well and and simple graphics are elevated beautifully.
Only improvement I could think of that when killing the enemy you would control the one that saved yourself instead of switching back to the past self that died. It can get a little confusing at first but I did get the hang of it afterwards.
Very nice game and polished beautifully!
