Planned improvements

[high] Multiple spawn points

There should be at least 4 spawn points, corresponding to each of the quadrants in the game.

Up to 8 spawn configurations could be possible, if the snake has a chance to go in two directions.

It can be taken steps beyond that, but the outcome should be:

• makes game more fun (more varied)
• more conditions / variety to explore in ML environment

[medium] 2+ render targets

A console based interface can be built using blessed or similar, enabling play of the game at command line.

I would prefer to host it on Deno, so I may look at porting or wait for portability to emerge in the toolchain.

[low] Improve UI "shell"

The shell is kind of quirky and sometimes needs repainting if it gets re-mounted, for example.
