@Superku:
I understand you very well.
Great indie games also privileges gameplay and artistic direction and not overdetailled graphics to be able to finish the game.

But really some materail textures would do the job, some 2 or 4 seamless textures per theme would od the job i think !

It's not big work t ochange the texture you use by just another one


In fact simple seamless material texture instead of actual texture would do the job !
And i think you can find free ones on internet to use !



Anyway , amazing ... keep it up !
