You should see a "Travel" button when you're in the city view. If you don't, it's likely that there was an issue during save patching, try reloading it
Glad you're enjoying the game :)

If I leveled up above 9 in v0.1.7b and then transferred the save to v0.1.8b, would my level stay as is or would it be recalculated to 9 due to the level cap?
When v0.1.6b was released, I played so much that I leveled my characters above 20. Unlike the lazy Kazuma, I like to raise my level to a point where my enemies are nothing more than ants ready to be crushed. ;-;
It would be recalculated and capped at 9 right now. Unfortunately I've got some rebalancing to do with the addition of new content and the new quest system so it's a necessary evil to keep things on track.
In the future, it's likely that we will have soft level caps instead of hard caps (i.e. you would only get experience for completing quests/slaying monsters close to your level), but that is still up in the air. The new system made it very easy to level up and render all challenges irrelevant based on the testers feedback so it'll require some careful tuning.
At least you give an explanation, unlike the original Konosuba author who keeps Kazuma as the lowest level quartet member in a completely inconsistent way. In Vol 6 of the light novel, Kazuma says he is level 17, and in Vol 13 he says he is still below 20, and even a lazy bastard like him had already killed enough monsters to be above 20 by this part of the story, He even mentions that he bought several XP-rich foods, but his level didn't increase.
By the way, do you have plans to add food that gives XP to the game? Maybe have Kazuma learn cooking skills, which is light novel canon?
