What's your Favourite 2D Video Game?

[bls1999]

PR2 is my all-time favorite 2D game. For the most part, I like all of Jiggmin's games better than anything else on the internet. I am a fan of "This is the Only Level" and a few others I've played through the years (Pandemic 2, Arrival in Hell, and Zombie Exploder are the ones I can think of off the top of my head).

I wasn't ever a *huge* fan of Happy Wheels. I did play a bit, but it never did much for me.
