If by soft locked you mean you couldn't select any other levels, that is because when you get "Game Over" you have to start back at level 1. I understand if that seems confusing. Thanks for playing I will remember that if I decide to develop this further!
By soft-locked I mean I couldn't figure out how to get out of the Game Over screen. It said press any key to continue, but I pressed a lot of different keys and nothing happened.
