Emerald Limit

Play as Cloud in a short, solo Emerald Coast speed course. Sprint between six gates, jump through raised targets, slash four training sentries with the Buster Sword, and beat your time. Two checkpoints help you recover from falls.

Requires installed Steam copies of Final Fantasy VII and Sonic Adventure DX. This native Windows reimplementation reads Cloud's original model, textures, animations and sword from your FF7 files, and Emerald Coast's original terrain, collision and textures from your SADX files at launch. Melty passes FF7's folder; SADX is found automatically through Steam. No original game assets are included.

0.1.0 is an early Cloud-only mini-course, not the full Sonic Adventure campaign or a faithful recreation of its physics. Keyboard/mouse controls; no multiplayer, audio, controller support or full wall/camera collision. The course has boundaries and recovery. Tested locally on Steam FF7 app 3837340 build 21140793 and SADX app 71250 build 411939.

WASD/arrows move, Shift sprints, Space jumps (again near a sentry for an air dash), J/click swings the sword, Q/E rotates the camera, R restarts and Escape pauses.

The planned cast is Cloud/Sonic, Aerith/Amy, Tifa/Tails, Barret/Knuckles, Vincent/Gamma, Cid/Big and Sephiroth/Eggman. Only Cloud is in this release.
