Graphics are ok, riddles to easy

What shall I say...
...very short game. I needed 10 minutes to reach the exit. The riddles are all too easy and obvious
It is for free, so that isnt a real complaint :)
Make the riddles more challenging.
What goes for the atmosphere, maybe add some ambient sounds fitting the surroundings.
Anyway, thanks for this free game
