The option to rescue the other slimes is a great feature if you feel bad killing the poor things, and its an added bonus that they also give you a temporary bonus for doing so. The game itself has a clear and persistent tone to it and it was definitely a game I can tell had a lot of thought/consideration when making it.

Very nice! I like how it encourages you to save your enemies not hurt them. Really great incentive. My only critique is that the bullets are a bit fast.

I really liked what you did here. Catching and using the slimes to assist you is an interesting concept. I would like to see the rope drag the slime in though. It would make it more contextually clear what's going on. Also the rowboat approach is unique. Good luck.
