I'ts such a fun game. The most engaging one I played so far in this jam. The gameplay just pulls you in.
There is a weird difficulty curve where if you let one person turn zombies the game becomes lot more difficult and you are likely to get more zombies which makes the game impossible. So the only way I found to "win" is to just get so good that you don't get any zombies at all, but then the whole zombie mechanic is skiped which is kinda a shame.
I think maybe this could be solved if the zombies wre quicker to spawn (so it's impossible to serve all tables in time and some will spawn for sure) and there was also some way to get rid of the zombies, so that there doesn't form a hoard which blocks you entirely and makes it impossible to play. But im not sure if this would be the right decision to go with the game.
All this to just give you some feedback, it's a rly good game, loved it a lot.
