This is awesome
1. Multiplayer
I know literally everyone is going to say this but I truly think you should be able to play with friends that would make the game a lot more fun and take it to the next level
2.Clans
Another idea a lot of people suggest but I think you should do this as a lot of battle games love to make the game about mainly something like this
3.Emotes And More Characters
Emotes are a STAPLE I repeat STAPLE of any battle or battle Royale game and some ideas would be losing emotes or winning emotes such as flopping fish, or the floss. Also more character ideas could be a LOT I’m talking like 65 characters and an idea for one could be Jackson a secret agent carrot
4. More modes
This one is pretty straightforward modes like 1v1 2v2 3v3 and such you could also do different modes like brawl stars with gem grab, or brawl ball, another idea is power play where each day their is a new fighter you have to use with tickets to get massive rewards and maybe add new characters each update
5.A sequel
Last but certainly not least a sequel I think it should be called, Food Gang 2: Lunchroom warfare and add even MORE characters with 3D models and make the maps look kind of like the one from I am bread
That was all my ideas and I hope you take the time to look at them :) ✌️
