It's a barebones demo so there's not much to comment about, but I like the digging.
You can fix the shader stutter by spawning one of each particle as part of the map-generation process btw.
What else do you have planned for this?
Yeah the shader stutter is pretty bad. I'm really looking forward to adding dungeon-type structures. Wish I had done that before this demo day
there's always a next demo day
