There’s a reasonable amount of variety in the victory conditions, but there could be more.
For one thing, maybe do stuff that forces the player to use different components of the game. I’ve hardly used the siberian stuff, and despite now finishing the intermediate level, I’ve barely used the multimixer or shaker. And I’ve never used either the sachet thing or the centrifuge.
- Use one of each ingredient. (forces to explore and develop lots of lines).
- Produce a single product that has 2,3,4 cure effects within it, all active. This will force use of the shaker/multimixer/sachet machine.
- Produce n products that have no side effects.
- Research everything
- Research nothing
- Analyze every cure. Or if that’s too much (probably), then every cure at a certain low level, or 4 cures at a high level.
- Build and use n machines (of a certain type?).
Needless to say you can mix and match. But the current ones are all quite samey.
