No problem it was fun ^^
I managed to get out of bounds by falling right from the end of the game. By doing so I managed to fall against the wall of the box and land in an area that had no spikes on the ground. I continued right and there was no collision on the wall which led me out of bounds. As far as I can tell you would need a lot of height to get there in the first place - so it might only be accessible from falling from only the end of the game.
