Very fun and polished entry !
The panic of building train tracks while the train is moving is pretty fun. Simple but effective design. The additional stuff (esp the trees) were where thought out and implemented. Had fun playing through the levels.
I made my train blue :3
The copyright free music is annoying to me though.
Small neatpick :
- The red arrows looks like a speed buff, not a slow. Once you know it, you know it, but it's pretty unintuitive visual language. Inverting the two colors would've made more sense (or change the sprite to something less that indicates a slow).
