This is the tileset that I used for my platformer.
This is the final mockup screen for my platformer. I had change the tileset to some snowy, winter tileset, and i also change the character sprite which i had done the animation before that so the game will fit my theme(snowy).
If you want to try out my platformer game, you can download it here:
