I recently contacted them about the app "Delight Games Premium" which is basically a collection of all their stuff. The launcher isn't accessible. They have moved on from the Choice of Games engine, with which they created Wizard's Choice, which was fully accessible. However, some of the other individual games, like Deep Space Huntress, if downloaded separately, are mostly accessible and use a new engine.
If you're at all interested in these games, please try them out and let the lead at Delight Games, Sam, know. See here for the address to write to.
Also check out this forum thread if you're on that board; I fully expect that's where the conversation is likely to continue for those interested.
