I played this for an hour during work... seriously SO good, from the intentionally janky controls that actually feel super good and fluid when you're playing correctly, to the hideous dragons (I mean that in the best way possible; the designs are impeccable and so unexpected), to the balance of having to come up for air vs getting blasted by fire, the progression tradeoff as you get bigger as it becomes easier to collect gems but harder not to get burned alive, the spot-on theming (I failed MANY runs from being greedy...), the difficulty curve. No notes except extremely minor presentation/audio stuff. Super fun game.
