Thanks for playing. It's ok to criticize don't worry that's what comments are for :)
"interacting with stuff very random" : There is a specific order to interact with items (chain of interaction you need A to interact with B to interact with C...) so there is a logic behind it, it's not random. So I'm not sure what you mean by "random"
"some items were practically invisible" But it was my intention to make items less visible by playing with the light/shadows! Sound is also giving directions not everything is visual. One of the items is not supposed to be visible before doing certain actions.... I think It could be better for sure (like adding luminosity/contrast setting because we all have different monitors) but it was never my intent to make items really stand out (shiny, or interact icons) I don't see the point of doing that in this sort of game
