Years ago, Sam Gabrielsson ran The Tower of Pin site (http://www.pcpinball.com) devoted to computer pinball games. However, he also hosted some other games that he had written as HAND Productions, and some of these were DOS games or Win9x screensavers usually involving cows. You can still get most of the files via the Wayback Machine:

Also, the Go community has promoted David Fotland's (Smart Games) Igo as a free introductory program for Go players, although it hasn't garnered a lot of interest since the advent of Windows and the Windows-oriented Igowin: https://www.smart-games.com/igo.html

Good read on the preservation effort & download of the unreleased 1988 DOS game Thrust.

Recently I've stumbled across quite obscure DOS games that have Amiga connections, but very little information in them is available:

(The) Puzzle Pits/Puzzle Pits '95, which I found via dosgames.com. It's a Soko-Ban variant with a plot of sorts, in a fantasy setting. I got stuck in one level and was trying to find a video walkthrough, but the only videos I found were for the Amiga release called Puzzle Pits II, which looks and seemingly plays the same, but has a pretty lengthy intro sequence:

The second game is a first-person grid-based RPG called Daymare I, which appears to have also been released on Amiga as The Mystic Well. The freeware DOS version comes with no documentation whatsoever, but the MobyGames description and screenshots suggest that the Amiga version might have had more features, like selectable character classes.

I'd appreciate any information on these two, if only just out of curiosity.

Recently I've stumbled across quite obscure DOS games that have Amiga connections, but very little information in them is available:

(The) Puzzle Pits/Puzzle Pits '95, which I found via dosgames.com. It's a Soko-Ban variant with a plot of sorts, in a fantasy setting. I got stuck in one level and was trying to find a video walkthrough, but the only videos I found were for the Amiga release called Puzzle Pits II, which looks and seemingly plays the same, but has a pretty lengthy intro sequence:

https://www.youtube.com/watch?v=drO3nMyRcjs&p … SBwaXRzIg%3D%3D

I've found a bit more info about this game. It looks like the Amiga Puzzle Pits II by Abe Pralle indeed came first and was a shareware thing. It was even covered in an issue of the CGW magazine (No. 112, Nov. 1993):
https://archive.org/details/Computer_Gaming_W … e/n115/mode/2up

Some bits of information about this game's development background can be gleaned from this snapshot of the "About Us" page on the former Plasma Works website:

Plasma Works was started by John Abe and Abe Pralle (hitherto referred to as John and Abe). John sat behind Abe in a chemistry class at Northern Arizona University in 1993. They didn't know each other (nor have they ever shared another class), but John spotted a review of Abe's Amiga shareware game "Puzzle Pits 2" (long story) in Computer Gaming World. The two soon found out they shared a common passion for and a common vision of computer games. They've been friends and game designers ever since.

The company appears to have been founded initially to port the game to the PC and sell it. I've no idea why the story with the evil wizard's spell was dropped in favour of a more vague setting where a wizard's apprentice needs to solve the puzzles for the sake of training his mind.

I was able to find the demo, which includes three unique levels, on an even older page of Plasma Works:
http://www.infomagic.com/~plasma/Pits/aboutpits.html

They included some pretty though levels in the demo, which they probably shouldn't have because I'm afraid that it might have scared the potential players.

BTW, I figured out the puzzle I'd got stuck at last time. It was using a certain mechanic that is never explained and you must figure it out on your own through trial and error. It's pretty clever, but again, I'm afraid that this kind of difficulty has not been conducive to building a fanbase for what is actually a very decent game.
