Thanks. I suppose the AFK thing is based on chance, as I have tried it a few times and it is possible to die, although the game could be a bit more fast paced for this to be improved. For the level length, I believe it is good as is. Some people said that the game still progresses too slowly, and since length is the difficulty factor of the game I think the levels could get longer even faster. I suppose that is based on personal preference though.
