Your physics engine has some serious issues. I will hit something and end up pointing straight at the ground, after spinning out. I also got stuck inside a blimp and broke when i barely touched the ground. Fix a few physics issues and this game would be 5/5. 4/5.
I think I know why the balloons are such a threat to monkeys. They are filled with antimatter. When the balloon enters the end of the map, it pops, annihilating everything within... 5 inches. Truly a threat.
Although it can easily be avoided with about 4 missile gatlings and 4 lazer gatlings.
I can also assure you that the pace of the game picks up a lot when you rank up further throughout the battles -- such as to Extreme difficulty. From there, you will need to strategize more and more as you fight harder and harder enemies and you may need to use the occasional Stat Reset (which are limited so you may not want to save until it works). It gets more exciting later on when everything happens much faster and when you accumulated your strongest skills.
Dexterity increases the rate that the bar recharges, and thus attack speed (if that was what you were referring to; Dexterity also improves the projectile speed of some attacks).
Strength increases Defense (reduce damage) and Intellect increases Energy Regeneration from using the Action: Defend (hotkey control). Getting more Levels also increases speed and defense and life and energy.
AI is a dumbass. Zombies seem obsessed with travelling in a conga line, and often follow this when ordered to move:
Is there an obstruction?
Yes: Walk up to it and stare at it!
No: Spin in a circle or vibrate like your fap-fap-fap-ing.
What would be really cool is if once you got very big another worm came along, hearts filled up the screen... AND THEN A SWARM OF BABY WORMS WAS TURNED LOOSE IN THE CITY!!! Controlling a swarm would be pretty cool, and lurking through the sewers and buildings would be awesome. Its a little much to ask, but if you could, at that point, let you dig out lairs where there was food to heal, and breed to make a bigger swarm (similar to normal upgrades) the city would have to be huge of course, but if you could possibly program in all of that, the game would be a 7/5. Its a 5/5 for me and always will be.
Im pretty sure Rejoy's score on "Levels Complete" is hacked. Last time i checked, there werent 500 levels. Ever. Not even in Pac-Man. In fact, only Nazi Zombies has 500 levels, because it has infinint levels, of course around lvl 20 the game becomes near impossible because of how ineffective your weapons are. So yeah. ITs hacked.
