I have read about the current financial status and while I don't have a solution, I do have a suggestion of how to improve it. The DRM-free market is growing and GOG is a pioneer in terms of that. While there is no guarantee the sales will be outstanding and solving the issue, a release of the first game in the series might help as many people seem to enjoy the second one already. This however does not guarantee anything. If concerned about the costs and revenue gained from such a release, I recommend at least asking the community in the forums if they would be interested in buying the game.
