Nothing to add that hasnt aready been said, Creature stage lags.
I used to love spore and i really enjoy this game too
Thanks for playing, and for the report!
The performance issues have been addressed and seem to be working well in the browser on my end. Most of my testing was done in the standalone version of the game where it's not limited to a single thread, so I apologize for the performance issues out of the gate.
A different marker, or an easier way to find the nest is a great idea. Thanks for the feedback!
