Rules of the game

Players must defeat the enemies falling towards the planet.
Each planet has HP, and if it reaches 0, the game is over.
Try to defeat as many enemies as possible to get a high score! It also has a ranking feature so you can compete with the whole world!

Specifications

Enemies attack planets in a variety of ways, so be quick to defeat them.
Even if you come into contact with an enemy, you won't take any damage or loss points, so beat them to the ground!
Don't forget to collect Exp, which you can gain experience by defeating enemies.
Also, players have a timed special weapon called "Ex Change" that can be activated by collecting exp. Use this to your advantage.

Enemy Characteristics

It's not strong, because just walking around the planet will drain your HP, but we'll take it down sooner rather than later!

<missile>

It's rushing towards the planet in a straight line, and if you don't destroy it before it does, you'll take heavy damage!

<Bomb Devil>.

If you land on a planet for a certain amount of time, it explodes! It has a large chance of appearing and a rather large HP, so watch out!
