thank you for the feedback and for playing.
The second mechanic is the truck on its path to the goal; the upgrade “break time” is one example that influences its movement (stops its motion). However, there are many more planned things like tracks that fork and have switches, reverse switches, speed changing etc. I think now that I spent too much time on polishing up the core mechanic and perhaps could have gone with 3 or 4 levels instead of 5, and worked on the truck mechanics more.
im hoping to make it to round 2 so i can further develop these (if the new task allows)
