Just updated Burrow! The second area now has more of it's own identity with new traps and new enemies. I'm still experimenting with it so feel free to give feedback but as it is I think it's comming along nicely.
Changelog:
-New trap type, spears
-Near enemy, beetles
-Modified spawn rates in second area
-Ant nests no longer spawn too early on
That's all the big changes, enjoy.
