[Mod suggestion] Increasing difficulty

[Joe78man]

Hello guys,

A thought:

If enemy expansion is difficult, at the beggining it's an actual threat, but it decreases as you get more options to deal with it.
If expansion is not a problem, at the beggining you are not in actual danger and later on the locals are just a pest very easy to deal with.

I was thinking about escalating difficulty based on your science. Not changing the behavior but the numbers (evolution rate, expansion, etc). Mostly expansion which is the real threat. If expansion accelerates (distance, minimun time reduced, more creatures make the expansion) for every new science bottle color, gradually, as you grow in options, so grows difficulty.
