When i first saw Nidhogg, my expectations were pretty high and I was pretty damn hyped. I was looking forward to a game with deep and extremely satisfying combat. Unfortunately the reality was a lot less. The game has a relatively high price tag for an indie game overall, and there is nothing to get your money's worth in it. The combat is disappointingly simple and somewhat stiff, the graphics are run-of-the-mill pixel art, there are only four levels, the single player consists of playing each of them four times and takes about 30-40 minutes. The game in general has very little to offer for such a high price tag. Give it a pass until it's in a bundle and then find a friend to play this with.
Not a bad game, but feels a bit more like a tech demo than an actual game. The way you can cut pretty much any piece of the level is really fun for a while, and can help you come up with outside-the-box-solutions to puzzles. It's short enough to stay interesting to the end. The other ways to manipulate stuff the rocket and the hook feel somewhat less pleasant. The way Tiny takes the device off his back every time you use it gets somewhat annoying. The other thing I didn't like was the art style, but that's a personal preference.
Wasted potential: the game. The premise is great and the physics WOULD BE good, if they weren't so unreliable. You'll find your character getting squished by the gun you spawned next to him when building your base. You'll find yourself unable to climb a ladder. The movement is awkward, which would fit the game if it didn't get awfully frustrating trying to do basic things. It has its moments though. It's something special shooting out one of the engines from a ship and watching it crash into the soldiers it just dropped off, or having your grenade launcher fly out of your hands after a fragment of your own grenade flies into it. You can't help but chuckle when your human soldier ends up squishing into the ground after you lose control of his jetpack. With a lot of polish and tweaking this would be a great game.
