Celeste, and some mixed feelings.
@Draekos I am bad at video games, especially platformers, and I beat Celeste without any assists. As long as you limit your goal to "reach the summit" and not the extra stuff, it's very doable, especially with the assists.
Also, the feel of it doesn't fundamentally change through the game so you can just stop if the vibe is bad.
Like, Celeste is one of the most forgiving in the genre, and Dread is one of the most brutal, from what I understand.
