General guide on getting all the achievements
Controls are Arrow keys to move (WASD also works) and N to shot ,B to change speed and V to change the orbital shooters direction
To change difficulty go to "Option" and its the first option available
For Normal clear - Beat the game on Normal
For Hard Clear - Beat the game on Hard
For Devil Clear- Beat the game on Devil
For Caravan Clear - **Survive 3 minutes in Caravan mode **

The hardest achievement comes from beating the game on Devil, luckily after you beat the stage once ,you unlock the next stage so you can try as long as you want until you beat each level
These achievements should unlock whilst you are going for the Difficulty related achievements mentioned above

**CHAIN 10
**
CHAIN 30

CHAIN 50

Chain 100
the following guide is for getting "Chain 100" if you did not get it during beating the game 3 times already
The trickiest achievement is Chain 100 and if you dont get Chain 50 normally you can do this as well
Go to Caravan mode and put it to the highest speed by pressing B a few times until it is max speed and then just shoot and dodge bullets. Took me a few tries to get "Chain 100" achievement.

After doing all of this you should have the 100% for this game.
