After much effort, I've fixed up many bugs and made many improvements to the level designer. I've also created 20 more levels and added more to the story.
Like many developers, I go through many "hate this game", "love this game" cycles.
Thanks for your support. I still fully intend on finishing this game. My moral is fairly high, and although this game won't make much money, I think it is interesting technically in discovering what is possible in reverse level deign for match 3.
I appologise for a change in the save file which will mean you will need to start from scratch. On the positive side, I have re-gigged the levels to improve them.
