Nice, I like the repeating pattern, it looks like old school games. 🎮

I suspect this is needlessly slow because we do not inline it.
| doN 6 move; | |
| // doN 6 move; | |
| move; move; move; move; move; move; |
I also tried replacing But do not do this, I measured it and wait with turn forward.wait is better!
Subjectively, the simulation seemed to keep playing better without lag on my computer once inlined.
EDIT: I will try to rebuild with profiling enabled and see if the difference is measurable.

Just following a blog post about profiling with cabal, I can see some difference in the graphs:
| Non-Inlined | Inlined |
|---|---|

@xsebek Great work looking at performance, memory profiling, etc.! We haven't paid much attention to it so far but I'm sure there is tons of low-hanging fruit to improve performance.
I'm not sure inlining things in scenario programs is the right way to go, though. Ideally we should be able to encourage nice, modular code and work hard to make that nice, abstracted, modular code run fast.

Maybe this could be a bit shorter? Though it does work well as a performance test. 😅
