This was quite fun, I think with more upgrade variations, and some additional content this will make for a really fun replayable experience :)
I like how you handled the animations for movement, really quirky!
I genuinely enjoyed playing this and managed to get a boomerang almost as big as the entire screen.
Fun little exploit is to get the ‘Loyalty’ one (healing when grabbing the boomerang) if you rapidly click the player haha, I used this in my second run
