Spring Lisp Game Jam 2026 entry.
A precision platformer with the focus on obtaining and maintaining speed.
Collect powerups, escape the caverns, and reach for the stars!
A write-up about the development process: https://andreyor.st/posts/2026-05-24-spring-lisp-game-jam-2026
Tips for playing:
- When doing extended jumps, release the direction buttons to avoid losing speed
- Press the slide button preemptively instead of timing your slides
- Release the slide button when under a low ceiling, the slide will continue, and you'll be able to jump immediately after (jumping doesn't work when the slide button is held)
- If you don't know how to make a certain jump, try doing it without jumping (????)
- Game menu features a static camera and an option to toggle off music
Share your completion time and retries!

Update 16-07-2026:
- added new camera: a blend between follow-the-player, and snap transition
- removed 2544 colliders that couldn't be reached by the player (optimization)
- merged remaining single-tile colliders into longer horizontal/vertical strips (optimization)
Update 20-07-2026:
- merged more colliders
Update 03-09-2026:
Major graphical overhaul:
- new parallax background with custom palette
- some foreground sprite fixes and changes
- new default camera that follows the player, with per room/region boundary
- background animations and proper color change for biomes

Made a TAS speedrun for this game with a few skips and some crazy movement https://youtu.be/OyRDwPJh-m4

Updated the TAS speedrun, making it faster by ~26 seconds:

great game, but I hate that I have to release down in order to jump. it makes things way harder for no reason

well, it's hard to jump from a sliding position... I mean, the character here is no Kazuya Mishima from Tekken nor Richter Belmont from Castlevania :)

I have a camera system that uses map() to draw the level, and it has a method for translating sprite coordinates from world space to screen space. So the camera object is both a rendering pipeline for the level and the objects in it. That's a general idea of how a single layer is rendered.
Because the camera draws from a set of coordinates, for parallax I shift these coordinates by a certain factor, and it gives the offset with which I draw the background. So, both foreground and background are just map() calls, but sprites for the background come from a different bank, which I have to sync() every frame. Since sync() works only once per frame, I have to draw the foreground, sync, draw the background, and on the next frame I draw the background first, sync(), and then draw the foreground. The order changes each frame, allowing rendering from two banks seamlessly. |
