hi
you asked for suggestions so here are my two pennies:

laughter in the background from time to time

percentage counter when cleaning up the beach (like on the huts so you know how much is left to do)

Picking flowers (someone else mentioned this I like it I second it)

More magic fish in lagoon (magic fish of healing, the golden guppy (only golden child can find) etc. et. el.)

possible bugs:

swimmers look like they are swimming in part of the beach (looks like my swimmers are up to their necks in sand)

when I tried the time skip (resetting my computer clock) my villagers froze (they just stood there doing nothing even when I moved them) I actually find this game is better with out the time skip.

thanks for hearing me out.

plh
