Had a good time, I liked the Wholesome narrator :)
Accidentally closed the window and lost all my progress though, ill have to come back to this at some point. I am sure you know about this, but the wall jump is a bit exploitable with roofs.
Also, about Z and S not working, it worked fine in firefox on linux
The wall jump roofs thing I was to referring to was that your jump seems to refresh on any collision with the world, allowing you to skip some parts of the game by just mashing jump as soon as you touch the ceiling, this lets your jumps refresh and you can stick to the ceiling indefinitely, with the help of the double jump mechanic
