If you fought the old version before this one, you should already know what the idea is behind this boss. If not, you should go play it at some point (if you really want to). Link is here: https://scratch.mit.edu/projects/429878152/
So for probably about a year, I didn't go back to this project because I thought it was unsalvageable, but I finally did it! I am thinking of making a remake in a similar style to the remake of swift patrol.
