Latest release · 17 Oct 2026RAMBEAVER — FM-1 release 745

RAMBEAVER is a complete action game for the M-VAVE FM-1: defend the dam, ride through robot city, fly to the data center, and defeat Mother. A flawless fresh run unlocks Golden Beaver.

Build 745 fixes forest ground texture extending into jump gaps. It retains separated jetpack-head launches, ‘Witness me’ every sixth ordinary kill, exact-progress saves, and the two-confirm Golden Beaver ending.
