marble machinations

(working title)

logic mostly like https://git.crispypin.cc/CrispyPin/marble

todo

(more levels) story/lore timestamps in solutions and blueprints multiple input/output sets undo/redo tooltips lock tile types for early levels to make it less overwhelming make a gui alternative to pressing R to rotate between tile variants scroll level list scroll blueprint list make marble movement more consistent (>o o< depends on internal marble order) decide on marble data size (u32 or byte?) blueprint rotation?

intro, basic mechanics

output a zero (marble, io)
output multiple numbers in sequence (digits)
output zeroes forever (looping, trigger, bag output)
copy the input (input)
copy only odd input numbers (comparator, flipper)

0-terminated list processing

calculate list length (math, bag input)
count instances of 5 in a list
copy the second list
reverse a list (bouncing)

user-friendly numbers

convert a number to decimal ascii
parse an ascii number
convert text to lowercase

advanced list processing

index a list
search a list
add two lists element-wise
sort list
