I definitely felt the energy in this one (the music is hyped up and there are a ton of fast moving enemies). The biggest issue I noticed was the jump seems to be a bit too floaty for this type of game -- I had a hard time moving vertically fast enough to not get hit.
Oh and a nice little detail I noticed was in the control menu you actually had the character in the background to control so you could see what each button did in context -- I really liked that :)
