Thank you! I'm glad you liked it :) Glad you liked the boss design as I've been trying to improve that a lot recently
I knew it's tough to use the weapons together so designed them in a way you can use each individually. And yeah the arm is useless. Maybe it should disappear after getting the rocket to make switching easier.
I was curious after you mentioned it so went and tried it and it is possible! Here's some proof I did it (ignore the death counter though lmao)
