Community Insight:

Can you please remove the apple timer.


Im not able to join or have someone join our game been trying for a couple weeks.


For us its hard to understand but the concept and pixel art style are great.


Its a fun game for when you just need a break.


Is there a certain wifi requirement for the multiplayer to work? We are all in the same network and we cant connect.


Online doesnt work if you have Wi-Fi with automatic changing IP address.


Immediately we started playing, but after like 3 minutes it just got super boring.


It was not a good very good game.
