I wish there were a button to reset the AI's "memory" without having to retire. After an hour of watching my bikes make it half way around level 6, then turning left into a right-hand turn, it gets frustrating.
It took me until about level 25 or so to feel like I was actually solving a puzzle and not just clicking around until I find the loose piece, but after that it got difficult quickly. The last few levels were amazing. I feel like the game had just finally started when it was over.
@Moczan The game is blurry on HiDPI screens (e.g. retina MacBooks). It looks like you switched from Flash to HTML5 for this game. I believe it should be a pretty easy fix to make this look right. I ran into this problem recently and fixed it using this reference:
