For its small price (got it for 2 euros or something) this game is well worth buying. It's nothing groundbreaking, even though it offers a unique time-travel based mechanics (more like just two parallel 2D worlds between which you jump to solve puzzles, oh, and you can stop time). It's pretty close to Braid, Limbo, Fez, Swapper and many other indie puzzle platformers where basically every next puzzle is a scripted thing which you just need to figure out.
I think it took me an evening to complete it (dunno why it shows I only played it only for 2 hours).. The artwork is good, music too, the puzzles are interesting. As with most puzzle games, after the game is completed, there is nothing to come back to - so well, no replay value, but for the small price it's fine.
I found 2 bugs and had to restart chapters 2 and 7 cuz I was stuck. Namely, in chapter 2 the plant for some reason wouldn't grow in the future after I planted it - the bug wasn't there the next time I restarted the chapter. In chapter 7 the cannon puzzle got completely broken for me. Namely, every vertical shot would result in a cannon loaded with a fireball, even though the fire wasn't running between the tubes - I guess this happened after I put a few balls on fire and shot them. Also, the water wouldn't extinguish the fire on the door after I shot 2 balls on fire at the door in a row. You can imagine that such bugs are especially nasty when you don't know how to solve the puzzle on the first playthru and still experiment with things to kind of "brute-force" solve it - only to find out that the puzzle is bugged. And no save feature - had to redo the whole chapter 7 once again and watch a walkthru - and it worked. Was also stuck with the phone puzzle in chapter 6 until I just watched a walkthru for that piece - didn't guess you can reach the lamp in a jump.
Anyway, a good game, 7/10.
I hope this will be one of the last games in this row of indie platformers cuz frankly I think people are pretty much bored with all of them by now, much like by 2002 everyone was bored with the RTS genre.
PS. Oh btw that puzzle where the kid breaks his leg and walks with a stick in the future - uhm, dunno it felt inappropriate somehow..
