fun game, the momentum and physics are near perfect and feel natural for a platformer. There were only a few criticisms I felt compelled to share, to make it even better:
1. being able to move while eye-beaming would reduce the amount of frustration of being off from the targets by a few pixels
2. The camera is annoying when you screw up: if I face backwards to reuse an eye-beam target in multi-screen-long horizontal rooms, suddenly I'm cut off from seeing where I'm headed. This gets more frustrating when going back to a static-cling wall, and now pressing in the direction I'm headed will most likely make me drop from the wall.
3. Had to fullscreen my browser on PC to see the whole screen, it was almost impossible to play without being able to see the top and bottom. My workaround was to just zoom out, but that won't necessarily work for everyone and it made the precision of the eye-beam even more frustrating.
4. SPOILER WARNING: I don't get the story's ending and I'm not sure that's my fault. What does the device do? Why does David's illness motivate him to use it? Who is drawing all the robots there, and why? Yes, I read the PC screens and info-posts, even the ones off the main path. I wouldn't say this is necessarily a problem with the story unless it was supposed to be self-contained.
