Very interesting game all together, I don't know Construct 3 so I won't worry too much about technical details.
The objective wasn't immediately clear, until I read the controls and pressed space, then it became kind of obvious. However past that point was just sheer luck, much like Blazing Sword Entertainment said, a more clear goal would be great, or even a subtle but easy to understand goal, there is a lot of ways to show a player they are advancing in the puzzle or doing well without a single word, just SFX. Speaking of which I loved the SFX aha, "homemade" impression SFX always win me over though :P
Above all else it was still enjoyable, although I wasn't able to complete it, I found the 5-10 mins playing around interesting and fun, and that's all a game really needs.
FYI I could pull things from 1 dimension to another as well, looks like a bug crept through the cracks.
