That one is deeply fun, I really enjoyed that. Having only a few shurikens looked harsh to me at first, but when I rewinded them to my hand again, I said that I don't even need a gun anymore.
Double jump made it even smoothier, traversing around is easier than it looks.
I found it kind of easy, but as far as killing enemies gives me joy, easier is better, right?
A greatly enjoyable entry for this jam.
