The Tower is filled with slabs of stone that move around the area. These slabs serve as essential platforms, but they’re also dangerous hazards. As you climb the Tower, take care to avoid being crushed between them.
The first Star Coin is in a small nook at Point 2. Stand to the right of the Star Coin, then duck down and let the slab carry you into the nook.
The second Star Coin is located past the door at Point 3. Before you head through the door, collect the 1-Up Mushroom from the Invisible Block on the left side of the enclosure’s entrance.
After you pass through the door, jump up along the moving slabs until you reach the Star Coin at the top of the room.
The third Star Coin is floating at the top of the Tower. When you reach Point 5, wait for the slabs to drop down from the ceiling, then wall jump up along the wall to the left.
When you reach the small platform near the ceiling, wait for the slabs to drop out of your way, then dash under the spikes and jump to the Star Coin.
The final chamber contains four Reznors on one small wheel. There aren’t any vacant ? Blocks when you enter the room, and after you clear out two Reznors the floor gives way. Defeat all four Reznors to complete the level.
