Logical (Amiga)

Logically, the Amiga version of the puzzle game Logical.

Hidden Message
The game contains the following developer note:

Dieses Programm ist in GFA-Basic 3.51D Amiga geschrieben. Ich habe nur eine Lehre daraus gezogen: NEVERMORE! In reinem Assembler programmiert wäre es fast ein halbes Jahr früher fertig geworden. GFA-Basic ist ein einziger Bug!

This translates roughly to:

This program is written in GFA-Basic 3.51D Amiga. I only learned one lesson from that: NEVERMORE! In pure assembler, this would have been finished almost half a year earlier. GFA-Basic is one single bug!

Apparently, GFA Basic was not very pleasant to work with.

As can be seen when unpacking the disk image, the game executable is called !logical (read as: NOT logical). This might be a in-joke by the developers.
