This is probably my best-rated game so far! It looks good, it sounds good (that *broop* sound when you complete a loop, niiice), and the gameplay is a lot of fun! If I had to give feedback for an eventual sequel / full-release, I would say 1) being able to pause the trucks while placing buildings & thinking would be super nice and 2) I'd recommend a monospace font for the HUD or making the HUD larger, so that it doesn't resize whenever the points count up (but that's honestly a nitpick and did not detract from the overall feel of the game at all). Great job!
