YES!
I finally managed (after 4 actual tries) to complete INFERNO IV with a KEYBOARD!
On these previous tries I had a lot of difficulty with the "incline barrel" part @ 2:10 ~
I might get back to it , but not anytime soon.
The only track left for me to finish is Frost Bite.
I hope you guys enjoy, I was so excited when I actually finished it ^^
