Super Meat Boy Retro Game References

[Donster Truck]

OK, I noticed a couple of nods to older games in Super Meat Boy: specifically, Castlevania in the intro to The Hospital; and Ninja Gaiden (I think) in the intro to Hell. Has anyone else spotted references to other games in there? Not including the unlockable characters of course.

I believe The End's opening is a reference to Pokemon Blue.
The Salt Factory's opening is a reference to the Adventure of Lolo 3, iirc

the forest intro is from street fighter (as far as i know)

The minus worlds are a reference to a bug in the original Super Mario Bros. One of the levels in Hell is based on Donkey Kong. Not to mention all the guest characters, including Braid's Tim, The player character from Minecraft, and a Headcrab.
