Hard not to compare it to the many others of this type. I didn't see anything original really. I also didn't get to any rewind mechanic at all?
I did find it very frustrating that escape returned to the main menu from the buy screen.
Yeah so holding space rewinds the time. Sorry about the escape thingy - I just didn't have the time to set up more UI for leaving the game. About the difficulty - I was intending for it to be hard so that the player would have to learn more about the game but I myself have noticed while testing it after submission that it was a bit too hard for the regular player (Notice that I have been playing the same thing non-stop for a week so it is only logical that I started to get really good at it). I suppose I can't do anything about it now((. Anyway, thanks for the review and if you could, please try it again with the rewind mechanic.
