This is a wonderful game, the most incisive take on builder mechanics I've seen. A few bits of feedback, most of which echo things other players have said:
* Resource-based failure detection has a pretty reliable false positive when building a greenhouse near 0 that nets you enough to keep playing. See attached screenshot below.
* I'm finding I often run out of trees before I reach the pollination goal in phase 2, and the game doesn't offer any guidance as to how I can build in this or the prior phase to avoid this. All the other mechanics offer pretty clear built-in learning experiences like, "arrange your rivers and wetlands carefully to contain fires", whereas I don't really know what I can do to earn myself some breathing room for the tree+bees goal. It's possible I'm missing some point of strategy here though.
* The "continue" button on the game failure dialog doesn't seem to do anything.
* The "exit" button should ask for confirmation, and/or its caption should be amended to clarify that it means exiting the game entirely.
