Bug I found: Money needed is at least $2350, buy boat upgrade ($100), buy 3rd Flag ($1000), and you can buy the 4th cannon without unlocking ($2600 if you have to sell 3rd flag and buy again so you can buy the cannon only if you don't have enough starting money).
this game is somewhat realistic as a survival game, zombies can destroy your current clothing currently equipped, food spoils (water spoils too fast, yes drinks too), limited backpack slots, and weapons has durability meaning they can be destroyed after a several usage. And lastly teddy bear(s) can be used as weapon.
I can say that they improved, but the improvement made the game worse. Please bring back the old system of this game and I'll gratefully play it for hours.
To those who what to get the gentle giant badge easily, you'll need to mute the tab if you reached 100x so you'll not worry in red notes. (when you mute the tab in firefox, notes will not spawn.)
