This is the kind of game I'd spend hours playing as a kid.
I was fearing every level could be cheesed given I could beat the first few levels with just a wheel, but on level 6 things took a turn! I'm currently stuck on level 9, I don't know if I'll be able to beat it, but I really want to!
Very fun game!
I don't know if this is me but is there any sound on the game? I see audio options on the menu but I can't hear anything.
Some criticisms I can give:
I really would've liked the ability to move existing components, given it's hard to know where the edges of a rectangle will end up when you are building it from the center, so the additional option to move it would've helped a lot.
Also, the ability to zoom out, I felt like the camera was a bit too zoomed in for comfort, sometimes my thing would jump out of the map and I wouldn't be able to tell where it was supposed to go.
Another thing I noticed is that sometimes, while building, especially right after coming back from racing, the thing would just start wobbling uncontrollably, making it hard to select anything.
Other than that I think this game has a lot of potential, it's easy to understand, the interface is very clear and concise, and it's really really fun! I spent about an hour trying to beat it, so that should count for something :).
