Beautiful short game, and the ending is so touching.
Have you any intention to make a longer game?
A Linux version would be appreciated too.
Compliments from a middle aged man who liked your job so much.
I have noticed three errors. The first one is at the begin of the first level, where the character can come back endlessly in the left wall. The second one is this time count with recurring decimals (I took a screenshot). The third one is that when clicking on "exit", nothing happens.
