For next release
^^^^^^^^^^^^^^^^
- add joypad controls to tehtriz x16 version
dpad left = "," (move left)
dpad right = "/" (move right)
controller B/Y btn = "Z" (rotate counter clockwise)
controller A/X btn = "X" (rotate clockwise)
dpad down = "." (descend)
controller B btn = " " (drop)
dpad up (and/or controller X btn) = "C" (hold)
controller start = F1 (new game)
make the 'R' tilemap a backwards R :)
- vm: intermediate code: don't flatten everything. Instead, as a new intermediary step,
convert the new Ast into *structured* intermediary code.
Basically keep the blocks and subroutines structure, including full subroutine signature information,
