GRAZE: Edge Rush - Score by almost dying. One tap, one shared course each day.
by•
A one-tap arcade game built on one idea: points come from how close you get to the thing that kills you. Graze a lethal edge and your multiplier climbs to x16. Coast safely down the middle and you score nothing at all.
The daily course is generated from the date, so every player worldwide gets an identical run with no server involved. Resets midnight UTC.
1,700 lines of vanilla JS on a canvas. No engine, no assets, no build step. Free on iOS.

Hey PH 👋
Every game punishes you for getting close to the thing that kills you. This one pays you for it.
One tap. The closer you graze a lethal edge, the faster your multiplier climbs, up to x16. Play it safe and you score literally zero, so the optimal line and the terrifying line are the same line.
The part I'm proudest of: the daily course is generated from the date itself. No server, no level data, nothing downloaded. Every player on earth flies an identical run. 100 people are on today's board already and it's open until midnight UTC.
Built as a single HTML file, about 1,700 lines of vanilla JS on a canvas. No engine, no framework, no build step, and not a single image or audio file: every shape is drawn at runtime and every sound is a Web Audio oscillator.
Free on iOS, no forced ads, no IAP - https://apps.apple.com/us/app/graze-edge-rush/id6785326186
Tell me what you score, best all-time. I'll go first: 48,345 (I am still the reigning champion)
Happy to answer anything about the architecture.
