0.9 Demo Update (last update before 1.0 release!)

All newsPlayers around this dateRead on Steam

Thank you all for playing the demo and providing us so much helpful feedback.

One of the main feedback was the prestige upgrade system felt too linear.

We changed the prestige system so now you have more choice in which upgrades to get.

With the new prestige structure, your playtime to complete the full game will vary depending on your experience with tower defense or idle games. Of course we will balance the game as much as possible to avoid overly OP upgrades.

We project 1.0 to launch this Spring! A formal release date announcement will come soon so make sure you wishlist and follow the game to stay updated.

Other updates:

  • Added Korean language support
