Celeste
Celeste is a game about a girl named Madeline, who decides to climbs a mountain, but her "evil" other half of her, Badeline, creates a ton of hurdles for her along the way. The message is really impactful, and the main character is trans! But best of all is that it isn't a big deal or a part of her story at all, and I love that!
I have 100 percented the game before, and even gotten a golden strawberry, but that was on Assist Mode. Then, I worked on a save file where I use it minimally (Working on getting Crystal Hearts so I can get to Chapter 8), and now I'm on a file where I use it only at impossible roadblocks and have it off otherwise (I'm on Chapter... 7, I believe). I've also finally started on my 100% non-assist mode save! I think I'm on Chapter 5. I'm not even trying to 100% it right now- I just wanna beat the game first. But I'm having fun and enjoying myself, so what's the problem?
