I really liked the toy-box style visuals and the concept made for some very interesting and rewarding puzzle! The music worked nicely in the background too! The puzzle design was great and I especially liked how they each led into one another! The map design also looked great too and the little indicator for each car worked well! The camera controls also worked nicely!
I think the controls were a bit confusing and needed something that would work with perspective in mind, maybe dragging each car with the mouse to move them instead. Some animations also might have been a nice addition.
Overall, I really enjoyed playing and this is a great puzzle game!
