I've been wanting to update my game folders but I don't know where to get some more.
I'm up for horror, adventure, RPG, etc. as long as they are free.

Personally, I enjoyed playing Don't Escape, Imscared and Calm Time. (spooky)

If it's okay, will you suggest me some Free Indie Games?
Also, if it's also okay, no games from Unity because my laptop is horribly outdated and will lag.
And yes, I am aware of GameJolt.

I've also played RPG Maker games like Ib, The Witch's House, Mad Father, Misao, etc. majority of the games vgperson translated..

I think most everything i've played, everyone's already played. So you may be better versed in these than I am.

Have you tried Desert Nightmare? That's a fun little RPG romp.

Out of free indie games if you're into city builder/survival and horror I suggest Rebuild its free up to Rebuild 3 which is a massive overhaul of the entire series. There's also a great horror game called Cry Of Fear however its a bit old so you've probably already heard about it.
