Incomplete mechanicsToday I spent a few hours pulling together the prototype thermal mechanics. There are now two plant varieties that spawn and may potentially die off. However, I'm not sure how to turn this into an actual game... despite some time spent fiddling with the constants tuning it so that the butterfly has a significant effect and the plants have a useful behavior appears rather tricky.
I still have some time tomorrow, so I'll see what ideas I can come up with that might be useful. Lessons learnt from this - I have a tendency to try to make things with ill-defined or overly complex mechanics, and maybe something easier to nail down would be better?
