I'm a sucker for the original Arcade Volleyball and E.V.I.L. blows it out of the park! The added extras, cute sprites, environmental "hazards" (e.g. flowing water) are a really welcoming enhancement.
So it is an instant purchase for me and I dearly hope a multiplayer non-BETA version will arrive one day. Because this gameplay concept needs to be experienced against a human and you know it :)
