Congratulations with this one.
Nice game. good puzzle building. Like you said, short, but that's ok.
The opening tune is nice but the one during the game gets boring.
The graphics are small. It becomes pixelhunting and that's not necessary because there's a lot of empty space. Try to zoom in on it and make everything a bit bigger. I always thought these dorm rooms were too small and you never could fit your stuff in but in yours it's a luxury ;-). The graphics as they are now (not the pixels I mean) are alright. The characters are good, furniture is ok, except for the perspective. On some objects they don't match.
Because there aren't many objects I expected them to be interactive. But a lot is not (the mat, the bed, bedside table etc). That makes the puzzles easier.
But overall I had a few minutes of fun. I can see this as a part of a bigger story.
