Hey!
Thanks for making this game!
The idea seems fun and it's a nice interpretation of the jam's theme.
Overall, the game feels a bit unfinished and lacking of a core gameplay loop to keep the player engaged. I got two flood warnings and after surviving those, there didn't come anything else. I could keep picking up stones and sticks, but the music had ended and nothing really happened in the game either. Also, walking into the sea didn't really do anything?
I would've loved to see the player having to use the stones and sticks to actually build the city and wall somehow and having to replenish them as waves from the water keeps removing them. Currently there isn't really anything to do in the game except walking around on the two screens.
The start menu is also offset a bit weird, it's not centered and the options button doesn't do anything.
