Bombing Busters

You can unlock the Wind Boss, once you completed all of the 5 regular levels from the Wind World.

From now on, the bosses can move to one of the other 3 edges on the map. The same rules still apply for the dead zone and hit zones.

Phase 1:

Tornado Attack: He flies to one of the 4 edges and then creates tornados in all the rows in front of him. They will move from one end to the other. He also drops a wind crystal from the sky. This crystal will charge up slowly. You can destroy it with one of your bombs. The more time passes, the bigger the explosion will be, when your bomb destroys the crystal. If left alone completely, the crystal explosion will cover the entire arena, killing you instantly.

As soon as the boss has landed in one of the 4 spots, run up to him and drop a bomb in front of him. That way, the tornado attack will be stopped on that row and you can focus on where the crystal lands. As soon as it lands and it is safe to go to it, go up to it and drop a bomb and keep a bit of distance. This is the only attack for the first phase and the best way to damage him.

After 5 hits he enters Phase 2, which starts by him flying up in the air and circling the arena. He will create a giant tornado in the middle of the map. Out of this tornado, more smaller tornados will start to come out. These tornado will begin circling the arena in 3 different circles. Below is a screenshot that gives you an idea. Walk into the spot where my robot is standing and pay attention to the movement of the tornados. They always move in the same circles, only the direction in which they go is random. If you find an opening, walk into one of the circles where the tornados are moving and walk with them. Match your speed with them, if you're too slow or too fast, you will die. That is the only way to survive this. Don't bother trying to stay where my robot is staying in the screenshot. The tornados can hit you there. After that, Phase 2 begins.

Phase 2:

Tornado Attack+: This attack is exactly the same as from phase 1, except instead of one wind crystal, he drops two of them.

Do the same as during the first phase. Drop a bomb in front of him to hurt him and stop one of the tornados and then work on destroying the crystals asap. If you managed to survive the phase shift, this phase shouldn't be a problem anymore.

After another 5 hits, this boss is down for good.
