That's not to say Nidhogg is a bad game as is. It just feels like its current state is a cool little PvP component for what could potentially be a much more compelling single player experience. Imagine Nidhogg with a greater variety of enemies, weapons, and environments. Not to mention shields and armor which could increase durability at the expense of mobility. A few scripted visual story beats would add a lot too (à la the original Prince of Persia) or Out of this World (Another World for those of you outside the USA).
Sadly, it sounds like the creator of Nidhogg is more interested in online play and the whole E-sports scene rather than making enhancements to the single player component. Again, I don't want to be too hard on the guy. I know this game spent a long time in development and I'm really glad that it has finally become available for anyone and everyone to try out...it's just Nidhogg could be so much more, I think. *Sigh*...C'est la vie!
