Best package of quality assets to start:
-Trees
-Bushes
-More trees
-Big tree
-Funny tree
-Stones
-Platforms
+ mushrooms
+ glowing flowers
+ parallax background
This contains DEMO scene based strongly on Unity's 2D Platformer
Note:
This pack is graphical assets in png large format. The demo scene is just for interactive preview.
This style based assets will be more soon. I'm open to suggestions.
