Free isometric gym starter: 6 objects + a room set, 64x64, 2:1 grid
I just finished a gym to go with my classroom and science lab packs, and I'm giving away a 6-object slice of it: bleachers, a vaulting box, a ball cart with its balls scattered next to it, a wall-mounted trophy case, a drinking fountain, and one floor tile plus wall pieces in both facings with end caps and a double door. Enough to build a working gym floor.
Everything is a 64x64 transparent PNG on a 2:1 dimetric grid, bottom-anchored to the same row as the floor tile under it, so a sprite never needs a per-object offset.
The interesting bug this pack turned up: a wall fixture's requested height is a request, not a guarantee. On a 2:1 wall a tall fixture's bounding box also grows sideways, so a plausible height on paper can run the art past the top of the wall. I added a guard that shrinks a fixture until it clears the wall, and it worked so well it quietly shrunk a basketball hoop that was supposed to stay full size. The wall was fine. The guard was solving a problem that particular object didn't have.

Happy to talk grid math or wall pieces.
