Hi, I have played 0.2 version for a long time, and it seems the mouse occasionally double clicks when I suppose to single click. It doesn't have the same problem when I use the mouse elsewhere. The frequency is on average about once per dungeon, which is really annoying (I failed the game many times for this). Using the left button on the laptop has the same problem, so I think this is not due to my mouse (maybe due to my laptop).
No matter what causes this problem, I suggest a new feature for DD: always ask the player to confirm if the action leads to death. This is helpful and easy to fulfill.
