Update 1:
Hi! I've been working on the game on and off, and the game is a little bit more fleshed out. The idea for the game is completely fleshed out. First a ( really short ) video and after that the story.
Story:
You are employed into someone's mind/memories, to help him/her to accept his/her past. This you do by going into the memories and changing the scene in such a way that fits 'accepting' the situation. Depending on how far you get, the more colors ( emotions ) you unlock and the further you get into his/her mind. These emotions are part of the memories.
Most of the basic shader choice is done, and I've gotten better and better at scripting! I personally love the color wheel where you choose the color you want to activate. I'll start working on the memories and the puzzles behind it. I want the rooms to be somewhat connected to each other, you sometimes need a piece/object from another memory to solve another.
That's all for now!
