The v3.0 update has been in the making for almost 6 months. It took longer due to several unexpected bugs.
This update will come with:
7 new regular enemies
2 new bosses
2 new levels
Better UI
Some graphical improvements
Rebalancing to every existing level and mechanics
And more...
The Update v3.0 will be free, but will come with an increase in the base price $9.99, up from $6.99.
