This game really surprised me!
The first 3 levels i was just bored, i tought it was going to be another generic puzzle-ish wall thingys that i dont know the name, anyway, when the new mechanics were added i was like: wat?bombs?portals???dafuq???
The score system is really nice, you lose points when you "walk" through the path you left, it feels kind of tron-ish, loved the score system.
The effects were neat, puzzles were challenging, mechanics are amazing, missions that arent just getting to the exit, music was gorgeus but for some weird reason, when i played the game, the music barely played, dont know if that is a bug.
Anyway, nice music, nice effects, nice mechanics and challenging levels, i see no reason to rate this less than 4 stars.
I could talk more about the game and my opinions on that but i got stuck in a level and cant see the other mechanics and missions :P.
Welp, overall i give this game a 4.5/5.
