That is a nice particle effect.

LGE runs on Pokitto?

LGE does it for you through its builtin particle system.
I suppose it’s just points with position and speed updated using simple explicit forward integration: x += vx; y += vy; vy += gravity

You caught me! :wink: It’s running the same C code… but compiled and linked to SBDL, API calls going through a wrapper API pretty similar to LGE’s. So no VM nor interpreter nor anything fancy going under the hood. Just the bare minimum to get the code running and be able to debug using good old Codeblocks and my own tools on an old PC. It’s much faster and uses less RAM. I could lift some annoying restrictions on sprites and code size screen resolution… but breaking compatability isn’t on my mind :grin:

I’m sorry, I forgot to include the game source code for LGE:

Just copy/paste into the code editor, it’s easy :wink:: https://corax89.github.io/esp8266Game/index.html

Works in the Pokitto HW too. I could not get to scale. Also, the binary is in dev mode, which means that you cannot any more launch a loader for loading other games.

Oh, I did not remember you are using MinLib. There can be a different way to start the launcher. I have not used it myself.

Otherwise the demo works well in HW. It is always fun to see what you have implemented :slight_smile:
