This suggestion applies when you finishes an upgrade to something to max (5/5), all of them cost 2500 coins and only one can be equipped at a time:
Damage : Your Pushes also deals damage and you get a punch frenzy where more you attack, the slightly more damage you deal
(frenzy ends after 1 second and you deal the regular damage again)
Sprint : Your speed is unaffected which means that your keeping the same walking and running speed
(which could be good on jumprope and red light green light)
Guard Earning : No
Glass Inspect : You can decide which glasses you can see (Instead of being the 5 first it's the 5 of your choice )(having the pass gives you 1 push, use it wiseley)
Health : Your HP gets tankier when killing someone (your maximum HP gets an additional 10 HP which means 100 + 10 HP for each kill you do for the current game) (resets if revived though)
Tug of War : You get a pull item to pull other players during games where you can fight (you can pull foes toward you, they also fall so it's easier to hit them)
Jump : You jump slightly forward (like the mario 64 forward jump) and every 1 or 2 Minutes your jump makes somebody else fall by jumping on them
Knife Damage : Damaging an enemy with the knife (or the fork) deals bleeding damage
(Bleed damage deal small damage overtime and ends after 1 sec)
By the way mods, i get it, i won't be mean anymore, alright :]
