I really like the game. Maybe Bosses at every 10 or 50 or 100 levels would be great... with rare drops maybe. Bosses could be slower than you so you could step 2 while they step one or there could be an accessory or doughnut for that to make it a bit easier...if it would be hard anyway. Xd I don't know I would like to see more and stronger monsters too as you go deeper in the dungeon.... so more dungeon stuff...and for idling players maybe some level skipping options would great too then(?). But there are so many other things you could add...like upgrading your "base" thing with new buildings and stuff. There are lots of possibilities but whatever you would add Í will check it out. :)

more bosses, or base development. Tick.
