It's not bad. It's got fairly okay gameplay, and the time-travel thing is used well, albeit unoriginal.
There is no plot, and it seems like a desperate attempt to make an art game. Try harder next time, for it to mean something specific. Greywolf below was a dick about it, but he's right. It's too much like Braid, the gameplay is not very smooth, and the little quotes n the signs are slapped on and with no meaning. Again, try harder next time. And for the love of god, don't name it Dusk.
The storyline is supposed to be open to interpretation huh? Well here is my interpretation, there is no story and you have thrown around cryptic phrases in the hopes that people will read more into the game than what is really there or at the very least pretend that they get the meaning behind the game in order to appear more cultured, just like an Emperor wearing a tunic made of invisible silk for fear that he would appear unfit for his station if he diddnt, am I far off the mark?
As for the gameplay there is nothing new here, there is not much to differentiate this game from the original which in itself was little more than a poor man's Braid, in fact the gameplay even seems to have taken a step backwards as this game seems much more glitchy than the last and not quite as smooth.
I guess on the plus side though the music was kind of ok.
I thought the ending would have more of a moral to it, but it was still a neat game and I love the music for it. It's very fitting.
There is a bug when you suddenly lose your time control ability ( the music stops at the same time). Reload the page fixed it for me.
Minus half of a star because of that bugs ( it left me confused when I thought it was part of the puzzles :P)
The first one amazed me enough but this one even tops that, good job sir.
