I picked this game up when it was on a free and was amazed by the quality - didn't actually realise if was on a special promotion at the time, so I have now sent a donation which you thoroughly deserve. This is an excellent game and I've really enjoyed it, the difficulty is so well balanced - I almost always felt like I was making progress of some sort, very little grinding but some good puzzles and challenging areas.
I thought I was on the cusp of completing it but it appears I don't have the third crystal - I was sure I'd completed ever dungeon but apparently not. I don't suppose you could give me a clue as to which dungeon the third crystal is in as I can't seem to find it!
As a suggestion if you are planning an update and if it's feasible, is to make the crystal-containing dungeons you've already visited show on the main map with an icon to show if you've already got the crystal from that location. But anyway, it's a great game, very nicely done!
