The game looks really varied and cool! The main idea for it is shared with one of the puzzles of our games, so I understood what you were going for.
The first 3 puzzles were really good and clear - but the one with the chains got me completly stuck - I literally couldn't find the doors! I think the 1st and 3rd one had the opposite issue - the environment is nice, but you barely have time to look at it if you solve the puzzle too quickly
Anyway, amazing job for 1 week, well done!
