A Fabric mod that restricts block breaking to a 2×2 tunnel, making straight tunnel digging easier.
How to Use
- toggle mod on via keybind or command
- start mining in the direction you want to 2x2 mine, it should automatically calculate and then only let you mine 2x2 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.
