Slide over tables by dodge rolling toward them!

Save hearts for later when at full health – pick them up at the new heart dispenser located at every floor entrance and shop (note: stored hearts are reset each floor!)
Added teleporters to more rooms (including chest rooms and exit rooms)

Turbo mode – delve into the Gungeon to find a new NPC who can enable this high-octane mode
