NiL 1:

This is a maze game featuring our favorite builtins: moving water, ice, and invisible walls. As you can imagine, these elements combined create a frustrating experience. But wait there's a time limit, and it's pretty low considering there's a screen full of invisible maze. Oh well, at least seeing Matt's dead face at the game over screen is worth it.

NiL 2:

Same thing as before, except instead of the invisible walls, there are killfloors that make you restart. So good luck remembering them if you ever plan on making it. Also, everything is a searing blue. And uh... I don't understand why this even comes with palettes, since it doesn't really use more than 3 colors at a time anyway...

All in all this is a collection to be avoided. Unless you want to understand the depth of NihilistMatt's masochism. P.S.: You don't.
