This is the very first build of a concept demo, not even a fully fledged demo just a basic semi-playable game idea, there's nothing beyond those doors hence them being locked. the only way to explore the unfinished areas past locked doors is to go to the testing area by press the tilda key ("~"), typing "t" and hitting enter to be ported to the testing area that allows access to portals to unfinished areas, :3
Once there are things past those doors, i'll make a lockpicking mini game to get past them, :3
