Grass Planets is a casual mobile game made for Webedia Games where you have to maw tiny planets to unlock new biomes and stuff.
It was mainly designed to be satisfying so the main point was to get the cleanest cutting feeling we could achieve on mobile.
On a technical aspect. The main challenge is too display dense grass fields on mobiles with a solid framerate. After some experimentations, this was achieved by tweaking Unity’s particle system to display grass blades as static particles, moved by a vertex shader. With this process, the whole grass for a planet can be drawn within a single draw call.
