It's too difficult to beat in one sitting, and you didn't make it so you can save. In the future, if you want to make levels that you aren't going to let people play, just don't publish the game. Telling people about them and making it so they can't actually reach them is just annoying.

I have to disagree, because all the levels are beatable. I've had multiple people playtest and most took around an hour, which to me is one sitting. While i can agree that some levels are annoying and could be designed better, they are still beatable. I know for many that driving in the isometric perspective is difficult, but that is a fundemental part of the game. So to me it just sounds like you have skill issue. That might be a bit harsh to say, but based on the other comments and my playtesters they seemed to have been able to beat the game despite being annoyed.
