Thanks for the feedback! I agree that I could have used the growth power significantly more, I wanted to get some levels that showed a variety of things rather than repeating the same principle of 'move box here, grow box, jump on box'.
That sfx bug is pretty annoying yeah. It's because when an object unloads, it doesn't call the function to turn the gun off. Easy fix, but just noticed it too late.
Thanks again for the feedback!
