Well I know the graphical stuff yeah. The Fat line on revolver was my mistake too lazy to explain all the dirty details but blame me on that. Wall texture was found on internet and I think its pretty good. But after all this was more like presentation and is going to be tutorial to show 2.5D elements that aren't documented yet like shooting and enemies.
Well it should be the newest version with maze and at the end there is 2 enemies guarding artifact (First had 10 but the engine well game got bugged and didn't allow me to have more than 2). I removed the minimap to make game a lot harder (It wasn't easy for Indy neither
As I said this is too complex and hard work compared to what you will get at the end so im sticking into 2D. Going to make 2D Indy game which is probably going to be a lot better.
But thanks for your opinions still^^
