Long input lines apparently interpreted as multiple commands. Crashed once with segmentation fault unexplainably in the middle of combat. Uses macros to save space, unfortunately in lowercase making code harder to read. No major problems. No code documentation, sparse comments.
Rooms created are persistent.
No crashes were encountered. Sending large amount of data to the MUD then later dropping link seemed to trigger a strange error condition. Commands are in all-uppercase, everything which isn't a command is sent as a say to the room, which can be a bit embarrassing. No code documentation but lots of comments. ADA is also highly readable even for one not familiar with it.
