I pressed quit instead of continue :(
I know. But I had 60 energy which is quite enough for at least 1 more room.
For now scoring system is much more hardcore. For good. Before it was like a chore when you could allow to farm hearts on early stages and you knew you'll get full energy for the next stage. But now you need at least lvl 3 to start farming hearts or you'll quickly run out of battery, but higher stage means higher chance to meet vibe killer, even a whole floor of them, so you are constantly on the move.
