Thanks for playing the game :P
This was my first boss fight I've made so I didn't really know what type of attacks to do (I don't play many boss fight games myself lol)
I think it thought of the circle attack pattern from very common bullet hell games. I kinda thought it would be cool if they spawned in one at a time instead of shooting it all at once and it worked out ! The other envelope attack was inspired by a game I played on cool math games xD. If you have any suggestions that would be useful for future games <3
