Hi there, long time no see.
I want to inform you that I'm still working on the game, but a new dungeon-crawler mode is taking too much time due to my day job, and there is still much stuff to do. Thus, I've decided to provide a smaller update with a bit of in-game content and bug fixes. The next update, I'm working on, will provide a few new game mechanics, which could refresh the game experience for you while you waiting for a new mode.
Here is a little spoiler:
Thanks for your patience and sorry for such a slow development speed. Stay tuned.
