Not bad, but the singular option for the controls is atrocious, esp when all of them are jammed together. (WASD, then X for action, then R for restart when impossibly stuck, etc)
I do wonder if there's another ending since I took the easy way out at the "end" of the last black and white stage I played, but can't be arsed to go back through and do it again. Had some browser trouble again. Worked kinda-sorta fine one time, but another it blocked me on that weird Circle-Splash / Metal switch stage (the first one) playing on another day. So very strange. Always seems to work fine on IE, but I'll be condemned if I'm always gonna play stuff on IE.
Anyway, thought the music was better in this one, even if it was a bit sparing and itself a little silly. Absence of decent controls, no level select, no progress saving (none of these games do), and bare bones all around suck any fun to be had out of this, but I think with a little bit of effort, you could make something of this.
It feels like there was a point at which you just thought, "enough of this, either it's just going out as is, or it's getting dropped." I've done the same thing several times myself, which is why I've never bothered finishing a game before myself, but it's also a good reason why I never stop getting... well, in my case it's self-criticism. In this case, it's plain for the world to see. Just a little bit harder, a little bit more, and maybe, just maybe....
