IMPORTANT
There's a bug with Marketplace that when you trade every copy of an item, you lose it, including upgrades, after restarting the game.,
In later stages, you might experience a memory leak, probably related to damage numbers. A temporary solution is to disable them or restart the game.,
Sorry for that!
We're working on fixing those issues as soon as possible.
We will address other topics as well, but let us focus on those first.
As a side note:
If your demo save didn't import, see this thread: Demo save
Not everyone realized you can hold left click to auto-hit bosses and to auto-buy structure upgrades. We need to add this info somewhere in the game.
Another thing easy to overlook - to unlock other boss rush challenges in Arena, you've got to upgrade the building.
Last note: a massive THANK YOU! We're trying to keep up with all the comments. Love reading your theorycrafting, it's insane what's happening.
