Very difficult first game

The first game I have built using Unity Engine by myself. All you have to do is to get the red cube to touch another bigger red cube on top of the platforms. That's it. It's simple, but super frustrating and difficult if you can't get a grip of it.

All the sounds and music were also done by me.

Controls: WASD

ESC to pause or restart.

You will have to restart a lot...
