I have been looking at all of these games featuring a lone-hero wandering through rooms with some sort of pending doom following them. There are 2d ones and 3d ones all being creative.

The way I see this game the creator is literally making art-work in real life and then recreating this art-work within the game itself.

I have seen 3d figures being painted/textured with real paint colors and being sold as fine-art prints. Looks nice on the outside but again these are prints.
This game-creator literally is doing the same thing.

Make the real-world creations, and then redo it in 3d. My question is then "How much of the artwork actually makes it into the game itself? How much of it is a replica?

This game literally ( I mean literally ) could be ported to the Sega Saturn, or even NES via limited colors.

Another innocent character that is pointless with a pointless threat. It looks interesting enough as something unique but I imagine them later putting all the artwork on display in a fine-arts gallery. That is what I see from this. Forget the game, imagine when a collector buys all of there stuff and it becomes the next Andy Warhol.

At least it is not Ori and Wisps creators ( who have in the past a bad work environment ).
