Yep, that was it. :)
Nice job! Especially within two weeks. I liked the low poly style, works very well in the game, and the little details like the buried tracks. the music works well too.
The gameplay was a bit same-ish though. There isn't much skill involved, I wonder if it could be a bit more engaging. Maybe that you had to jump over things to get to places, or something that would add a bit of variety to the gameplay?
