I dont know how thi sgame jam works but heres the link to the game I made:

 https://www.roblox.com/games/17842673611/Mr-So-Sigma-Tower-Defence-Boss-Fight

Youll need two people to play, one on offence, one on defence. The defences roll is to stop the suit man from destroying your towers and the offences roll is to attack mr so and stop him from destroying a great wall. a gun is provided for assistance. Certain towers will give you more economy(money) and the gatling and miniguns to extensive damge to mr sos fragile hands. 

Welcome to Mr so Boss battle, 

a boss fight in which you will be tested with your friend to fight

 and conquer a fancy Mr So. You and your firend will need to work togehter to use defences

 and offence support to beat mr so and his suit man and eliminate him before he can destroy all your weapons and defences. 

Can you work together with your friend to beat mr so???

Good luck.
