“Inside” is a pretty crisp game from the Letsplays I’ve seen. Its a linear 2D horror game slidescroller and has a minimalist art style that it pulls of pretty well. It also shouldn’t be that taxing on your machine since there never are a lot of polygons on screen at the same time though i never ran it myself.

Don’t be terrified. It paralyses you. Instead take your fear to a protest and see all the other afraid people. Then do something so you don’t have to be afraid anymore.
