Nice game. Visuals are simple, yet provide a good background. I like how the skeleton's head flies off when you jump. I had a hard time with the flying ghosts you need to press no keys for because by the time one appears, I am always into the rhythm of jumping as soon as I see something coming and almost never failed to collide with the first one. Maybe if every round started with a gravestone, then a ghost. Not sure if it's just me or I need to play the game more to remember. I also instinctively thought at first I had to press down to slide under the ghost at first since that would normally be the case in an infinite runner.
