Instantly liked this - windowed and gives you the keys to use - so excellent :)
And then you went up the wall - Terrific \o/
My only complaint is its so easy to become disorintated and not know which way is up or anything - that spoiled things quite a lot. My thoughts would be to limit to just walls and to maybe have some different texture so you know what way is the floor, etc.
But I loved the puzzles and the bow and everything else ;)
