Interesting...
I didn't expect much of this game, mostly because of the name. Boy, was I wrong! The flash doesn't have a discernable plot, but then again, it's not supposed to. I was a tricky platformer...
The levels that got me were the ones with THREE layers, like the last level. All in all, a two hour experience for me.
I like how the game messes with you. You're expecting more, expecting a decent conclusion, an explanation for Steven, a hint of what's REALLY going on...
...and you get nothing. But it's okay, because the maker MEANT to screw you over!
Although, if I HAD to try to make it make sense... I would say that the bad end is where you kill yourself and Steven escapes, and the good end is where you confront Steven, recombine, and leave the box. But that's just what I think.
Kudos on a great game!
