Build 0.0.3.4 brings several new things including a new level (3-4), improved story graphics for several screens, and kind of surprisingly, parallax backgrounds for World 2 changed (front layer of tombstones added, hills lowered). See the video if you don't have time to download and try for yourself:
Honestly, I'm not sure if it makes it better or not... But the old graveyard background felt too empty, so even if this isn't the solution, it's a step forward.
All recent changes pushed to demo branch too; new levels not available in the demo.
