It's a short single screen platformer where the code also fits on a single screen. You'll probably get through it in 30 minutes, maybe an hour if you take breaks to chew through your controller :) There is no life system or anything, you can try each level as often and long as you like. My daughter helped with a bunch of levels; I'm quite proud how it all turned out, it plays the way I wanted it to. And Fuze is quite good for stuffing a lot into each line; only the builtin function names are a bit long (a good thing, usually!) and the control structures are overly noisy; luckily, many if statements can be replaced by algebra.
Almost full playthrough:
The "real" program is available under the download key U8B73M5M21.
A version where the code has the same structure, but variable names have been lengthened and comments and sensible line breaks have been added is D8B63MND51.
Original WIP thread is here: https://fuzearena.com/forum/topic/1742/single-screen-platformer-ninja-gal/11, so I'll keep it short here.
