So much fun! And a real challenge too. The level design is absolutely fantastic! And I love the sudden realization that you have to kill yourself to progress, not only is it an interesting shock factor but once that wares off, it's a really, really interesting mechanic. I love how the red and blue eyes have different ability levels and how you have to sometimes control all 3 eyes at once! Also, the animation on the eyes rolling, as well as the graphics in general, are phenomenal!
Literally only two small suggestions for ya. First off, it was a little annoying that you'd have to restart a level if you accidentally pushed a box into a corner. To counter this, I'd suggest either adding the ability to break and regenerate boxes if you push them against a wall... or, maybe decrease the box sensitivity, so you don't accidentally shove it in a corner just by trying to get up on a ledge
And second, I think the game could benefit from a little more sound design. Just little sounds here and there (like maybe for the eyeball rolling) would go a long way. I totally get technical malfunctions with the engine though, that's no fun! I appreciate you still including the music! It's very well done :D
Oh also, love the portal references :) If you do more with this game, you should totally put a parody easter egg... "The Pie is a lie" ... or... wait wait wait. The P(eye) is a lie!!! xD xD xD
Great job with this!! I enjoyed it a lot!
