Well done for doing it in a week! Some of the doors required a jump through because you couldn't walk through them. Additionally, certain walls or floors lacked colliders. It took me some time to realise that the E key could be used to slingshot myself. Although I couldn't Spiderman my way through there as I had hoped because of the grid layout.
I eventually made it to the You escaped message at the bottom, but I immediately dove into the lava to test it. which took me back to the beginning (which I should have expected). Would you like to play my game? Its very enjoyable I promise :) You dont have to though its up to you!
