It's difficult, yes, but it's just so damn fun for some reason. Very addicting for some odd reason. Difficult and a bit unfair, sure, but worth it if you want to beat it.

You have to look at this in 2 different ways. In terms of actual design, it's a 2.5/5. However, if I based it on my enjoyment, it's probably a 3.5/5, maybe even a 4.

It's very difficult for me to rank, but I'll go with what my gut tells me.
