I just found a new bug although this one is using one of the cheat codes specifically oneshot. If you complete the game and go the debug room, you are able to crouch on top of the completion overview things and with that open the pause menu. But there is no way of closing the pause menu since the pause button is disabled by oneshot. so you have no way of removing this pause screen and no way to exit back to the main menu (you are soft-locked).
Also update on the StarfixHQ community SoB, It's currently at 1:58.67 which means that we have broken the 2min barrier :)
