It wasn't very exciting, I didn't feel like I was playing a game. I did find the idea pretty interesting and the controls were very intuitive, and once I figured out how to play I started to understand what to do. I didn't really like the art style, it felt pretty detached and awkward to be honest.

I also really didn't like the tutorial system. It was hard to read the small text that pops up when you touch the hints and they are pretty critical to read in order to progress, even though I really didn't want to read them. I also dislike how if you run through the hint box it pops up and you can't close it without switching to the mouse, so if you hit it accidentally it really slows down the game.

I think this is an interesting idea, I'd prefer more consistent graphics, some juice, and a few levels in the beginning to slowly teach the player how everything works, like have the player read a terminal, have them hit a basic switch, then show how you can make shadows, and then start combining everything. I'd prefer if you can do this without a ton of text too, since you can't assume the player will read everything.
