I love to play these escape games, and I enjoyed playing yours as well.
Negatives:
I wish it was longer
I will kill the music
On a side note, someone oughta sue that roller rink for not letting you leave.
(EDIT: I came back and played this again seven years after initially reviewing, and I still stand by my statement about the music. Thankfully that can be shut off. That being said, I feel like this game would be a great introduction for kids to learn how to do escape rooms. The art style and simple puzzles and mathematics would work really well for a child in the 5-10 age range.)
