Not many. The obligatory 50% of all mobile games that I played for 5 minutes and went "I hate this", obviously. But PC games? Hmmm. Probably "Lost Ember", I guess. What really puzzles me about this is I played "Spirit of the North" and was utterly in love with it, to the point that it's in my top 5, and "Lost Ember" is very similar in many respects. I ought to have loved it, and I cannot put my finger on what I didn't like about it. I just didn't like it.
