Good one! Liking the art and the music is a bop! First game I see here made with the Scratch engine! Didn't know that it could do stuff like this! Great job!
Didn't know I could press Spacebar to switch weapon, but figured it out after the boss fight. I did also end up looking for 5 minutes straight everywhere to see what I needed to do after the boss even though beating it is the current end point.
With some polishing, this could be a very nice post jam game!
