Transform into a Pretty Girl, Square Root it!

"Transform into a Pretty Girl, Square Root it!" is a pixel-style shooting game. Players control the enemy's health using a minus gun and a plus gun. The goal is to reduce the enemy's health to a square root able value. Once achieved, players can use a dash attack to eliminate the enemy, causing area damage and restoring their own health. 

The ultimate boss is a boos with a decimal point, which can only be killed by constantly dealing damage to it.
