Really short, the fact that there were zero levels where I had to use any thought bothered me. The whole game felt like the intro levels to a more complete game. The music was okay, but much like the game, it was short and repetitive.
The physics worked as advertised though, and I liked how momentum remained even when teleporting.
allot of ads, made me go to 2 sites because I'm used on clicking on a flash games to see if i'm able to skip the intro..
There's only two splashscreens, one is my sponsors, and the other is mine as a developer. Its only 5 - 10 seconds, it helps me get credit for my hard work :)
