Even in the starting location, everything is blocked off. You have to walk around everything. If that is not terrible enough, the game does not prevent you from re-blocking yourself. For example, you can push a block back to its original location to block yourself again. If that is not bad design, I don't know what is.
Like others mentioned, the game itself is pretty short. However, the game is not over after the credit roll. There is a new clickable element on the main screen (complete different area from the main menu) after the credit roll. Click on it to start another chapter!
