# marble machinations
(working title)

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

## todo
cleanup: unpowered texture names x_off -> x
sim/speed control gui
(option) display input as numbers
scroll output
default i/o text modes specified per level
properly center view
make marble movement not order-dependent (`>ooo <` does not behave symmetrically)
blueprints
scroll level list

decide on marble data size (u32 or byte?)
blueprint rotation
