that just sounded on my head: after depth 30, if the group manages to pass it, then the group would find a boss every 2 levels or so, with new kind of bosses, old bosses with changed sprites and stronger attacks, and so on. For gameplay reasons, both the defense and health of the monsters should be capped at some level, to ensure that, at deeper levels, you will always kill the same monster in the same number of hits (maybe 20, saying that health of a pink jelly is capped at 200, and their defence can reduce your attack to 10 damage, at most, for strong weapons, and 2 for weaker weps/guns), but, instead, improving move speed (capped), charge speed (capped), and damage (not capped, probably a single hit from a pink jelly against a knight with 300 normal defense and shields up would cause enough damage to kill the knight 10 times at depth 50). And, finally, considering the linear advance, i calculate that, more or less, depth 40 would be the equivalent of depth 30 at the arcade, what is good.

Fast levels, with decent rewards for the chalenge (not as much as arcade...we don't want to add a feature that will render another useless), but only clockwork tunnels (appart from boss rooms)(with all the monsters as a possibility, not only the ones of the CT)(a reduction in goblin spawn rate would be great here)(also, total remove of treasure rooms with key/energy lock).
