So first of all: the idea of the game is great and the puzzles you designed are all very interesting. But: it is difficult to navigate the world without a map and sometimes it is unclear wether a puzzle is difficult to solve, because I am dumb or because a level is broken (due to clipping objects). This quickly gave me the feeling of being overwhelmed.
Other than that: the art style is simple but works extremely well. Also the music is setting a cool retro vibe for the game.
All in all: Great game, but some pointers would have been great.
