I've successfully disassembled the LTG, LVL, HS/GHS and LPB formats, so I can make this new thing able to load them. The biggest planned changes, relative to the current LaserTank, are as follows:
- Raising the 65535 step limit for LPB files
 - New objects
 - Runs on both macOS and Windows
 - Alternate projectiles for the tank to shoot
 - Bigger levels: Grid can be up to 24x24x9, with stairs up/down, springs and pits as ways of navigating between floors
 - Versioned file formats, so that future changes do not break compatibility as much
 - All translations in one package, with the ability to add new ones later
 - Multiple concepts entirely new to LaserTank
