Tiki Dash is a free browser endless runner (lanes, jump, slide, coconuts, launchers, caves, rivers), built with three.js r184, Vite and TypeScript. No install, no ads, works offline as a PWA. I built it solo; the target device was a mid-range 2021 Android, not a desktop.
What mattered for the frame budget: merging the side forest into one InstancedMesh per species took the phone from ~770 to ~160 draw calls; after that, capping DPR at 1.5 did more than any geometry cut. Measured on a Galaxy A41: ~57 fps average, median 60.
Add ?hud to the URL to see fps / ms / draw calls / tris live. I’d like to know what it shows on your phone, especially older Android or iPhone.
