I tried it out, but it froze up my browser on Firefox + Windows on a pretty well-resourced desktop.
The page loaded fine, but when I hit "Play" everything ground to a halt, and even scrolling the page up and down had a 3-5 second delay.

Firefox has not been a focus for the game as it mostly ships on Chromium/WebKit based browsers/app wrappers, but the landing page should still work great.
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
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.)
