Amazing game. I've been playing for quite some time now, haven't finished the game yet, though I'm really encouraged to do so :)
The puzzles are pretty difficult, but very well made and the concept itself is brilliant. Especially love the idea of using other cars to carry your car. The visuals and music is really pleasant, they work well with the gameplay.
I have only two complaints:
- steering is very confusing (even after 20-30 minutes of playing) - either directions should be relative to the camera position or maybe it should be done via clicking tiles you want to move to with your mouse?
- the connection to the theme is very loose
It is otherwise an amazing game, without any doubts the best one I've played so far and I would be really willing to pay for a polished and expanded version of it. Really, really excelent job!
