Great sequel.
It's been a long time since I was last on NG, but anyway...
Lol. The red arrow concept was also in the first one right? I can't remember.
Then the green block thingy... it's new if I'm not wrong.
Those flying green circles are a pain to collect, as a word of advise I say that you shouldn't waste time to do so.
If you're ever writing a sequel to this, I'd recommend something like having amounts oh HP so that at least if/when you're careless you won't lose all your lives in one go. Well, it's just me but yeah.
OMG! Only one song...
The special power thing was original, fun, but I think you should decrease the costs accordingly to ... feedback.
And yeah, I end here. Good luck!
