I see at least 4 more doors on the top level but I already beat the game and got one of the mentor moves. Whats up with these sealed doors? Are these secret or unlockable levels or is this just extra space and something they never finished?

There's no way save right? I don't see the option anyway, you leave the game and when you start, you start off in the same room and go the through the portal and start the game proper. Can you buy ammo? the armory didn't have ammo to sell, Can you extend your inventory? probably right?...

So my save files (the entire streumon folder) are marked as read-only. When I uncheck read-only, apply the changeg, then close the window, I re-open properties and read-only has been re-checked. Legit no idea what to do, I've tried some OS-related fixes but all of them were already applied on my PC (I have the required permissions, controlled folder access in ransomware protection is off, etc.)...

Seriously, it would be awesome. Use Unreal Engine 5.

Is there a way to remove the MASSIVE camera sway + sound effect from landing after even a small jump? Jesus christ it's like some kind of tictok meme every time I land after jumping...
