Haunted Tophat65 ,

One of the greatest time wasters ever!

Words cannot express how much I love this game.

Powowksjjeieks ,

Terrible laggy fun.

I notice that the hitboxes are square, instead of being the ACTUAL PLAYER. Which means someone could be a starter's fish length from you and still kill you. Most of the time im being chased, and then suddenly it lags and im dead. ADS EVERY SINGLE TIME YOU DIE. IT IS SO ANNOYING. Greedy devs only want money

Terribly unbalanced

The game has very over powered power ups, played for awhile and had more than 2 times mass than the person in second and some very tiny person killed me instantly, make the shock or laser just stun and it'll be pretty good
