release notes:
100% version, fully playable, based on the unreleased preliminary version.
original save/load bug is fixed, level-warp cheat is reactivated.

the editor (press ctrl-e) is read-only in this version, so you can edit and play a room, but not save it back to the disk.
the "switch disk" option is not implemented in this version, but you can place yourself at the exit of the last room on the disk side, and then leave the room to cause the next side to be loaded.

complete documentation (maps, tips, bugs, keys) will be available separately.
