Instead of having a Left and right Missing to hit the exe, I decided to make it a full boss fight. How to beat the creature? Easy. Hit it 8 times. What do you imagine his attack patterns will be like?

and how to hit him:

Well, you have to make sure they're vulnerable, and then attack them. Then repeat it 7 more times. The bottom-right of the screen shows their hp (it's 5 in the concept art) If it's invulnerable, it will teleport, causing you to miss, so make sure it's caught off-guard after it's attack.

By the way, if you win.. it doesn't mean you "SAVED" them..
