Hey man, thanks for the feedback.
Firstly, I'd like to say that there are 0 interactions with LMB in the game, all of them are made with E. Can you please give an example of an LMB interaction? I'm genuinely curious if I've overlooked something by accident.
Second, I'm aware about the save/load system, it was just a test, I'll fix it in the full build.
Third, the textures on the blue walls are indeed a glitch with Lumen shadows, and I could fix it easily, but I decided to leave them there as a sort of reminder that what you're seeing/experiencing is not real (meaning the player character, not you guys). I thought it looked cool and fit the story.
Thanks so much for playing and for the feedback, it honestly helps a lot.
God bless.
