What 2D Platform/Shooter Games Do You Like On Wii U?

I'm big on Megaman, Contra, Metal Slug etc. and get a bunch of games on Steam. I pretty much have all the original Megaman, X and Zero games on the Wii U but was wondering what other cool games there are outside the virtual console. I know the run n gun genre is pretty much an afterthought and that only a few of us still truly love the genre but, there seem to be a great amount on Steam, which is great! We're talking about games on the eshop though. Is there anything worth looking at?

@-paranorman-: Shovel Knight, Freedom Planet, Mighty gunvolt etc.

Yoshi Woolly World is good shooter also. Star Fox Zero and Sin & Punishment are good 3D ones.

Gunman Clive is a great 2D platform shooter game that plays a lot like Mega Man set in the wild west. It's really cheap on the Wii U eShop too, only $4 I believe yet it is more fun than many $60 games.

Well, lets see...Castlevania II: Simon's Quest (I just acquired it again but have not played it for 20+ years), Child of Light (2D side-scroller roleplaying game, tried it out for a few hours after purchase, love it; but had other games I needed to finish first), Donkey Kong, Donkey Kong Jr., Donkey Kong Country: Tropical Freeze, Ghosts 'n Goblins (really hard old school 2D side-scroller), Kirby and the Rainbow Curse, Namco Museum (Galaga, a vertical-scroller shooter), N.E.O. (Near Earth Objects; a shooter similar to Asteroids), New Super Mario Bros. U, Super Mario Maker, and Yoshi's Woolly World. I want to get some Megaman games, Rayman: Legends, and Oddworld: New 'n' Tasty. I need to try some old Metroid/Metroid Prime games.

Other games from Wii Virtual Console: Black Tiger, Golden Axe, LostWinds (Wii Ware), Space Invaders, Star Soldier R (Wii Ware). Wii games: Metal Slug Anthology, New Super Mario Bros. Wii, Rayman: Origins.
