Glitch Buster

Play:

Maximise Touch: Screen splits into four tap zones: left edge to move left, then move right, throw a breakpoint, and jump reading left to right, with a pause zone along the top. Confirmed working with a held touch on a simulated touchscreen. · Keyboard: Arrow keys or WASD to move, hold Space to throw a breakpoint, P to pause.

About:

Built for js13k 2016's 13-kilobyte limit and placed 2nd of 60 entries Overall: you're a debugger inside a crashing program, squashing 13 pointer glitches by landing on them or throwing breakpoints before the code collapses. The title screen and in-game text keep the "buggy software" joke going throughout, rendered as glitching source code.

Touch is a genuine four-zone on-screen scheme (move left, move right, throw, jump, plus a pause zone along the top), confirmed working directly: a held touch on a zone visibly moved the character into a new part of the level with the countdown timer running the whole time. One quirk found in testing: the tutorial's dialogue only advances when tapped near the character/text itself, not anywhere on screen.

Phone check: played on a simulated phone (390x844, real held touch on all four control zones) and on desktop (mouse and held keyboard) on 7 Sep 2026 — movement, jump, throw and pause all confirmed working on both; zero page errors, zero external network requests
