The game is still not half way done (~40%) so there's not that much new content in the full version, but of course I will be adding more and more soon.
A new update is planned for the next week with 6 new enemies and lots of bug fixes - the update itself is based on music and sfx.
The update v14 (the one after this one) will have 12 new cards and 12 new monsters, as well as a new mechanic - Items. You'll find out more about it later.
After that, all the content for stages 3-5 will be only available in the full version. For now, the full version only unlocks some cards and enemies from stages 1 and 2, but later, not only new cards and enemies will be available, but many other different mechanics like items, taints, characters, achievements, game modes, and so on...
Once the game is like 60% done, I will be trying to upload it on Steam. Everyone who buys it here will get a key for the Steam version.
