Hey!
A real fan of the low-poly + low-saturation visuals. Simply sublime and also a detailed minimalist! Especially level 3, that was intense.
The game was puzzling, and that's exactly what a puzzle game should be doing to me. But I had a lot of "what should I do?" moments, and not many "how should I do it?" moments. Though the game is about revealing hidden environments, if end of each level had more clarity and uniformity (like the start selection level [Pick light bulb] -> [Place it in the hole]), dense players like me can fully engage in solving the puzzle, and not finding the puzzle.
On a brighter note, you really nailed it with the 3D aspect of the game and the reason as to why those two levels were discarded is probably the biggest puzzle of all.
Would love to see more :D
