The editor for Adventure Gamer. It allows you to set the game's name, design levels, set the player's attributes, and their inventory.

i am blown away by this *shareware* tile-based adventure game creation toolkit from 1995 called Adventure Gamer
built for windows 3.1, it allows you to create your own top-down adventure-RPG games using a drag and drop interface.
it comes with a demo game called The Gates of Macrohard, which plays like similar Windows 3.1-based RPGs of its time, like Castle of the Winds or Exile.
The editor is full-featured, including even the ability to export your game as a distributable EXE!
it appears to have been built with MS Visual Basic 3.0, judging by the VBRUN DLL included.
