X-It Again is an excellent remake of Psygnosis's puzzler for the Amiga, faithful in nearly every aspect. Profiles are used to save progress instead of passwords.
Much like Sokoban, most of the gameplay involves pushing blocks around to fill holes and getting your character to the exit tile. Instructions can be found inside the Documents folder, with some rather useful hints provided. All tiles are described in detail, for example glue tiles can be walked over but blocks get stuck when they are pushed onto them. Press the left control and Q key to quit at any time.
