Double Man

Solving level 3 was eye opening for me because it was the first time in my playthrough that I had to consider which side to focus on first. In the first two levels I simply focused on the left first, got the crate on the goal there, and then worried about the other side. When I tried that approach on level 3, I got the right crate stuck against the wall and had to restart the level. The level design is so open that at first glance it looks impossible to mess up, but that is how I quickly found myself restarting the level. The wall on the left side is specifically placed so that if the player solves the right side first, the player will still be able to move the crate to the goal on the left side. Once I tried the level a second time and saw that the crate on the left got stuck against the wall that cuts out while solving the right side, I knew that I was on the right track. Then I was able to do the left crate second and finish the level accordingly. It is that wall that keeps the crate away from the edges of the map, where it cannot be moved properly. This was the only level that I had to try twice in the game, because once I learned my lesson about blindly solving the left side first, I was able to apply that to levels 4 and 5.
