The way quick drop works is confusing, as mashing down doesn't really work, only holding it does, and the game isn't very responsive to pressing or releasing down. It does make the match-3 a little more interesting as you have to choose between holding down to get more blocks on the screen and reacting to what you get. Since the player's healing & damage per turn doesn't increase, while enemy damage does, the game eventually gets very slow as you have to heal more and more, and it takes more attack turns to defeat an enemy. At level 11 enemy damage and healing are very close. I don't know if enemy damage ever outpaces healing because I didn't bother continuing my run much further.
