Nevermind, I figured it out. It was rather simple. All I had to do was "If "Tile" is on screen" then "draw terrain "Tile" on minimap" and it worked.
The only thing is though, I used quick backdrops for a large portion of the tiles (I got tired of cutting and pasting tiles over and over again), and this ends up showing the entire batch of tiles all at once rather than one at a time, revealing huge chunks of the level that I don't want the player to see yet.
I guess I could replace the quick backdrops all with single tiles, but that really is a pain.
Edit: Anyway, here's an updated cap (with only quick backdrops shown on the minimap, notice how much of the level gets shown).

Time to start replacing those quick backdrops with single tiles, I guess. That is, unless someone knows a way around this.
Oh and btw, I also would still like to know how to zoom in more on the minimap if anyone knows.
