Long-Time-No-Puzzle, SG

It's been a while since I made a puzzle, about a month xD

Here's another one, excuse me I'm a little rusty!

Ends Friday, 3 bundle games no CV, as I couldn't come up with anything very good.

At first I wanted to make this really hard to find, but I figured it'd be a good opening puzzle for people! :D

P.S.

It would be a good idea to save this letter: "I".

P.P.S.

I won't be telling you to save the future letters, and I'll be hiding them better, so keep an eye out. ;)
