Honest about the demo
This is a real game and the loop works. It is not the final version.
The multiplayer is simulated for now. Matches feel real, but you're racing scripted opponents while we gather the feedback to know what to build the actual multiplayer around. The real multiplayer arrives once the format proves itself.
The demo is Android only, French only, and free. It covers a few starting points designed for complete beginners, enough to let you judge whether the concept is worth building further. The full learning path arrives in the final version.
If you play it, the most useful thing you can do is tell us what works and what doesn't.
