A very well made game good job on everything!

I really love your html games i can see all the effort you've put in to the code
unfortunately i would like to point out a few thing that haven't changed in your games
Mainly actually just one and that's the use of import from.
import from was introduced in ecs6 rolled out in all browser between 2015-2017(not 100% accurate data). That means that older browser will not be able to play this game their are a few solutions for this online. I personally recommend compiling your game with browserify.

sinceraly,

This game overall is good the code is good the idea is good but the gameplay lacks and that has to do with the games introduction you're presented with way to many options cut it down change the ui to guide the player (and try doing that without text) then make the introduction level short just plain jumping and maybe an enemy or so than build that up. another thing that this game lacks is feedback the feedback you get when you get hit or collect a purple coin you really have to note up that "wow collecting that purple coin must be important" or "dam killing that enemy felt good"

so hope you will learn from this game and continue to make great games
