I really think this has great potential as a mobile app, admittedly less so for desktops. The noises for getting the stars are very satisfying, and the thud of the husky hitting the snow is pretty funny. I think the game could really benefit from some simple music with a wintry theme, if you wanted to expand upon the idea.
I did run across a glitch where when I opened the credits with C I was unable to actually get back to the game, as the tutorial phone came back up and wouldn't go away - something to look into-, but otherwise great for what it is, I think there's a lot of potential here if you want to expand upon it. If you did wish to keep working on this for PC, may I suggest some keyboard controls? My wrist doesn't like the constant back and forth motions. I look forward to any future developments for this project.
