Tutorial Road/Infinite Avenue

At the beginning of the game, you start on a Lone Peninsula. If you walk down, you'll end up in Tutorial Road, where you meet Tutorial Sign. He tells you different things, such as your goal to take back Tetra Towers, and how rooms can go on for infinity.

When you progress, you'll end up in Infinite Avenue. Tutorial Sign will ask you to find the door with the house. (Go down at the first 6 intersections then go right).

When you find the house, Tutorial Sign starts a battle with you where he explains the basics of fighting. He then lets you proceed into Moth Trail.
