Too bad about the limitation, but this is still a very neat game!
The puzzles made me want to explore the game's mechanics and I think that's neat!
Something that did confuse me at first was the red buttons and green gates - I thought I couldn't interact with them since I was neither red nor green. Maybe a symbol or different texture could help?
Other than that, really glad you implement zoomed out cameras, helps immensely with the puzzles!
