Would be nice to see:
1) parameters in settings for
-skip floors till floor X, or even more complicated like skip N floors till floor X, skip M floors from floor X to Y and so on;
-autoprestige after X points earned, otherwise just respawn, or at later stages would be more usefull prestige for x10 points from previous or something like that;
-turn your party displaying in compact mode, like icons with health bar, when you have more than 8 heroes it's not "fun" to scroll down;
2) fix floor 87+ (enemies have infinite health/damage)
3) add buttons to buy multiply upgrades (x10/100/1000 etc)
4) add button to turn on/off prestige for that layer, it's actualy annoying to go to next level and turn off 5 autobuyers
5) add option to suicide, cause it's take too much time watching your 10+ rangers do nothing to single enemy, and he oneshot one per "turn" than your 9 rangers attack and so on... maybe something like option in settings for autosuiced if no enemy died after 10 or X attacks
