Marble Blast Ultra: 2 Open Source Clones Compared
MBHaxe's marble physics and collision code are built directly on OpenMBU's, ported to Haxe and extended with features OpenMBU doesn't have: cross-platform netcode multiplayer, a rewind feature, browser and mobile touch controls, and native builds for Android, iOS, and Xbox alongside desktop. OpenMBU remains a Windows-only revival of the original Xbox Live Arcade game and is less actively developed (sporadic) than MBHaxe (active).
