Fixed that achievement bug (I was copying the achievement settings from the last profile to a newly created one, facepalm). Also reset the score to zero when keeping playing after all lives are gone.
New setup is up, thanks!
The highscore per stage is a bit more involved, currently I’m only storing per set. That would include having to remember delta scores during playing (only count points from that level), and taking care that the order of levels is adapted. for. I’m also afraid that you’re basically getting the same score for every stage when it’s completed but the bonus points.
