i like the puzzle. its not like you are totally guided, but also not so hard that you couldnt figure them out. pretty basic puzzle what not mean that there are bad. i enjoyed them ^^also i needed a second run to win the game ^^.
but yeah i few things could be better. smaller things for me like invisible walls, and the ceiling is the same as all other floors, what made me thing i could somehow got up there...
but for me the biggest "mehhh" was that the hints and text are not rly good to see with there colors and size. and the right hint is also to long across the screen...only a little bit i think but yeah
otherwise i had fun solving the puzzles ^^
