Hey thanks for the feedback.
Great that you love the concept. :)
I had a lot of ideas in my head for the difficulty including making more levels, but I have learned this the hard way that crunching on the last few hours of JAM always ends up resulting in more bugs than features, so I decided to stop this when it overall felt a good experience. I am planning to take this into a full game sooner or later and your idea for enemies is great. I will surely work on that. Thanks. :)
