Also, I'd like to note that you can "punch walk" - or pressing s and walking towards a horde of enemies get you points even without the punching frame.

I forgot currently I forgot to add one code that makes the later additions vulnerable to explosions... I will change it and add new levels in the process.

I assume you are talking about the levitating jeans... To remove it, Use the drones (They are the best against floating targets that are rarely vulnerable to other weapons such as cocktails and bombers.) Floating disc also helps. Deploy the Instant Armor at the middle.
