Yup. Btw we already have a billion floors so no need for more floors honestly. Well 2.417 billion floors.
I like the game for how it is because it reminds me of chess in strategy and that's awesome. There can be new features added of course though so suggestions are always good. As for quests, we had a Google play quest system which was a kind of quest system, feats and other gamestore application but those quests were short lived . Feats can be done anytime but feats are feats and they are basically in game quest/achievement tasks. Also this game relaxing when you want to in Pve .
I probably agree for the multiplayer aspect though. I mean I don't mind the A.I battles but the real battles against players live could be fun. I understand the limitations of the game but in the possible future or another edition of the game, it could come to realisation. Who knows really. There's so many things to imagine.
