I'm so glad that you enjoyed Alkahest enough to finish it 3 times! There's going to be an update very soon that will add spells (triggered by combinations of gems), new enemies, a new area, some story elements, more music and bosses! (and of course, a fix for the infamous sign haha)
And I'm really excited that the game was intuitive enough to be learned through gameplay. I have a ton planned for it and I hope you'll try it again in the future!
