Got 1650 by tapping, then 3600 holding the keys. I think it's pretty boss to go beyond 4000 out of the blue, in 3 tries or so, though it depends on the random patterns. I had an easy streak around ~3000, then a confusing series. Consecutive Up/Down are harder than Right/Left, because of finger movement.

It would be nice with asdf, homerow style. Maybe you could even have 2 rings going on at the same time, for each homerow.

If you've played a lot of DDR or Guitar Hero, it's not too hard.

Some tips:

1. Don't look at the top of the screen - your mind needs some time register what it's seeing and react accordingly. Look a bit ahead - probably around 2:30 to 3:00 on a clock.

2. I find that tapping every key is actually easier. It helps you maintain a rhythm and reduces the cognitive load (do I tap or do I not?)

I painfully reach 36. Should I see a doctor ?

I had the same question. Until I found that I should press the arrow in the box, instead of the arrow near the bottom bar... (Ahh, I love other music games, and this one has no music?!)

Trick is to not do wrong _consecutively_ . By doing right lot of time your life increases (indicated in the bottom green line)
