Thanks for trying again, and I'm glad you had fun! A tip for wall jumping is to only hold the Jump button with no directional keys. This will automatically make you jump when you get next to the wall, letting you do the wall jumps super fast. If you really want to get end and see the ending cutscene you could try again using the wall jump technique I just explained, but I totally understand if you're tired of playing this game and don't have the motivation to play it any more.
