I was very surprised with the amount of polish this game has! I like the little cutscene at the beginning and also the effect on the menu buttons! The art work is very nice as well and the music and sound is good. The design of the maze is great and I think having to pay with a reducing stats to pass through the doors is a really good idea!
I was able to get to the sister in 1 minute and 5 seconds B-)
However i noticed the a reduction in vision doesn't really have negative effect as i could still see everything despite the grey filter on top.
Overall great game, very well done! : D
