People complaining about the ending need to play upgrade complete if they haven't already. In that game you click a button and it goes from a plain text screen at the end with no real congratulations to a buff pic saying you're awesome and you totally kicked butt. Seriously, that makes any difference in a game? And, well, I kinda liked the end because even though I got trolled I kind of got a smirk from thinking about all the other people out there getting trolled who would actually get POed at it.
The journey in this game wasn't half bad in my opinion. The later keys required a little bit of thinking about how the game is laid out to anticipate where you should go, not a whole lot but suitable for a flash game. Platforming wasn't very challenging except for one or two points, but it's fine for a game that's supposed to be more cerebral than cerebellar. My only real gripe is that movement was a little too slow to be completely enjoyable (maybe because I'm playing on a $2.99 piece o crap laptop, but others seem to have thought it was slow too). Run button, plz.
