About

Minecraft Alpha 1.1.2_01 is an incomplete version that has a far more brutal gameplay loop than the modern releases. The limitations and constraints on content make this an interesting and nostalgic version to play, but some bugs, glitches, and inconsistencies make this version downright unfair at some points.

While there are existing mods that address these issues, many introduce additional mechanics or major gameplay changes that go beyond the scope of a minimal fix.

This project aims to provide minimal improvement, focused strictly on small quality-of-life fixes without adding any new features, implementing any of the various unused assets, or compromising the brutal vanilla experience, leaving room for player ingenuity to overcome the difficulty.

• Falling Snow in Winter Mode worlds now has a less obtrusive texture.

• Furnaces will not consume the bucket when lava is used as fuel.
