Sorry the voice scared you. :) I know it's a little incongruous with the visual style, but voiceovers are so fun to make.
Yeah, the hawk-like birds are pretty aggressive. I was thinking of not including any in the rocket level, but... I just couldn't resist.
Thanks so much for giving it a go, and for sharing your feedback! It's always really satisfying to hear that someone liked my game enough to actually beat it.
