It's your world. Do what you want to do... when you want to do it.
There is plenty more to do in Siralim than just dungeon crawling. Maybe you'd prefer to try your luck fighting in the battle arena. Or perhaps you'd like to use magical sigils to summon powerful bosses to fight which grant unique rewards and tell a bit about the lore of Siralim.
Or maybe you're not in the mood to fight at all. Maybe you'd rather take in the ambiance of the tavern while playing a game of dice with the gambling dwarves. Or, if you're looking for a long-term project, you might want to craft an egg that will someday hatch into an ultra-strong version of a normal creature. If you're looking for an even greater challenge, you can play the game in perma-death mode where each battle might be your last.
All of that and more - with no limits. There's not even a level cap. Want to gain experience points until your character is level 937? Go for it. Siralim has no restrictions - this is your world and you can play the game the way you want.
