Yep, they already have physics (custom ones which you can make) but its in the works.
Custom shaders will be allowed too.
Have you bought the game, Rem?
Dynamic light is coming at the 'final release', I read
So is multiplayer support (Like those online FPS's)
Yeah, I bought the game
I don't know if this has been told yet but i'll put it here anyway:
The price will rise to €30 when beta is released
