Really, really old (2012) Balrog animation. I was floored when I ran into this while browsing around on Tumblr - I don't have a copy of this anymore and almost forgot I ever made it.
It only exists in 2024 because when you reblog, Tumblr makes an entirely new copy of that post. Some people had reblogged it, so it was preserved.
No moment in gaming will ever come anywhere close to that one scene in Cave Story where you realize that there's nothing you can do. No matter how long you stall and wait, desperate for any other answer, all that's left is to move forward. You walk out that door, watch it close shut behind you, and listen to that song as you regret everything you have ever done.
