this program is largely incomplete and not in a presentable state.
please be mindful when sharing it.
however, feel free to copy any snippets of code you find useful.

TODOs: (that i can remember right now)
- normalize and/or embed sprite type inputs
- settle on a network architecture
- fix lag-frames skipped-inputs bug
- detect frames when Mario is in a controllable state
- compute how many input neurons the network needs instead of hardcoding
- rewrite positions to be relative to Mario
'-> fix offscreen sprites sometimes being visible to network
- add some detection for enemies later in the game

naive:
- learn any combination of buttons, starting from title screen
- learn to run network without frameskip
- learn other games
