2×2 Tunnel Dig

A Fabric mod that restricts block breaking to a 2×2 tunnel, making straight tunnel digging easier.

How to Use

1. toggle mod on via keybind or command
2. start mining in the direction you want to 2×2 mine, it should automatically calculate and then only let you mine 2×2 in that direction.

the mod uses frequency analysis to figure out which four blocks form the 2×2 cross‑section.

if you need to reset it, you can use the reset keybind/command then start mining in another direction.

only tested on 1.21.1 so far.
