About

This game is my first Pico-8 game. It is also the first game I manage to finish after a few attempts with game engines such as Unity and Godot. It took me 1 month to complete the first published version. The Pico-8 restrictions allowed me to define a manageable scope for this game. In the end, I used the entire space available in the map editor and the spritesheet editor. The code uses every token allowed.

Absolutely gorgeous, loved the music. Any tips or resources for developing that wall jump?

Thank you <3

For the physics, I (obviously) looked into the original Celeste code and from there I took my own decisions for inputs and logic as I play tested it. I guess the important points in my implementation would be :

Applying a force to the player's velocity in the opposite direction of the adjacent wall. This force should take over the current velocity so that the direction is more predictible
When the wall jump starts, start a cooldown timer in order to ignore the direction inputs for a few frames. This make easier for the player to adjust its horizontal inputs and also makes the jump direction more predictible
The friction also really helps to make the wall jump manageable. When the horizontal input points toward a wall that allows wall jump, then set the Y velocity to a constant (that is way smaller than gravity). Only do it when the player's going downwards because otherwise it would interrupt normal jumps.

Hope that helps

Nice job! Great game. I had the same experience with PICO-8 helping me define a smaller scope for my games so I could finish things.
Well done! Hope to see more from you in the future.

Thank you @mac, I'm glad you liked it. Yeah it really helped in making "hard" decision such as cutting things out. Which often turns out for the best :)
