A very fun game, looks and controls very well. It's a lot of fun to move the spider around the cave. I am also impressed by the randomly generated levels. But I just feel that it is a bit to unforgiving. You should not immediately die if you touch a wall of the lower edge of the screen. In my opinion the player should have a few seconds time after leaving the edge before they die, to have a chance to get up again. Still, great job!
