Tower Base

The tower base is a secret level in the game. If the player uses a collectible item used to break blocks, such as a drill or bomb, they can go to the edge of the map and fall off the tower. Doing so will play a falling animation and will then bring you to the base of the tower. This level appears as "???".

Outside of the tower there are 2 items that will spawn. One will always be the helix wing and the other will be randomly chosen - between Matchsticks, Teleporters, Pistols, Cardboard boxes - so do not count on it being the same item every time. In the center where the player spawns after falling there is a pink staircase which the player can enter to return to level 1 of the tower and will start Hardmode. Falling in the tower base twice works only as evasion of enemies and collection of one Helix Wing and one useable collectible. Hardmode does not change once you enter the tower for the second time.

This is the only non-scrollable level, the player moves from one section to the other in "pages". (It doesn't smoothly scroll - every time the player reaches the edge of the screen and goes to where other levels would usually scroll, it abruptly moves to the adjacent screen.)

The outside of the tower is surrounded by a fire river that is 1 screen away from the outside of the tower in every direction. In the river there will be "Firemen", a special yet harmless enemy.

If you manage to go beyond the fire river (using a fire extinguisher or, more easily, a skateboard/sword), there is nothing but an empty cliff face...

...or is there?
