I tried it and was verry disappointed so far ...
firstly he uses uncompressed png´s right out of the render software (lossless jpg/webp would easily shrink the game size significant without losing any quality)
secondly it was over very quick ... took almost the same time to play than to unzip it

Calling it a demo would imo be more appropriate ^^
thirdly the models didnt look that good - cant point a finger at it but they look somehow off (also the masturbate scene from Kat and her "hairy holes" - yikes)
If there is not an improvment in comming updates - I cant see me playing it again
I know tastes are different - sooo thats just my opinion ^^
