It's very laggy on my phone too. (Several seconds input delay.) That's fairly normal for a game made in React though (at least the ones I've tried). Is the paid version also made in React? For some context, my phone is old (2016) but I do find it amusing that it can run this page with a physics engine and 3D rendering without any lag http://kripken.github.io/box2d.js/demo/webgl/box2d.html http://kripken.github.io/box2d.js/demo/webgl/box2d.html Your game looks great though, and the website matches it perfectly! Nice work (As an aside, I'd urge you to take the from-scratch ethos just one step further and make you next game without any libraries, or with sensible exceptions like Howler and Pixi.)
