Cool game, the visual are weirdly pleasant. Them hurt my eyes, but give a weird feeling at the same time. Maybe having some softer edge could make it a little better tho.
I like the presentation too, UI and transitions were nice.
I couldn't finish the game, cause one of my cubes just went through the floor and I could get another one :( So that might be a bug with the cubes that you want to look at.
A sprinting button could have been nice, some of the walking between puzzle felt a little long.
And at time, the lack of music was weird, feels like you always need a white noise of some sort in this kind of game, else it's WAY TOO empty, know what I mean?
But all in all, great experience, I think the visual exploring idea has a lot of potential!
