I tried the demo, and there appears to be a serious problem with the fullscreen effect canvas. The screen is really zoomed in and i can't see the main character at all.

Also, the window size is wayyyyy too big. I can't even move it around on my screen (1440x900) or see it fully because the caption bar is cut off at the top when it starts. I'd limit it to around 1024x720 (somewhere around there) so people can actually see the window.
Aside from that, great work. I love the game idea, but i'm wondering if construct can handle it effiently. And please make sure the gpu requirements aren't over 512 mb.
