give the full amount of vision right from the start instead of having it gradually come into view. Trying to dodge a rock that spawns at the start of the level before you even see it isn't exactly fair if you're trying to get the dodge everything achievement.
Maybe have a setting that lets you auto-cocoon a percentage of the larvae you produce each second. It would save the trouble of having to manually make cocoons every so often to get a reserve big enough to make the cloning spell worth using.
is it possible to win on even chieftain? I feel like the rate at which your population grows and the rate at which you get stone is too slow to accomplish the palace in 100 days. This slow rate practically forces you to employ into the "high risk" zone and the events that occur either help a little or hinder a lot. seems like a lot of balance isn't there
