Patch 0.4 hasn't addressed the problem that people have been complaining about. Ending the demo after an arbitrary number of delves is just frustrating.
Let us keep delving, whether in forest or in mines, however much we want. Use our feedback to get the game tuned in to the direction that you think is best, and then lock progression behind a paid version (e.g., we can't get past level 4, but we can keep playing at level 4 all we want). That's what we're asking for.
