the music n sfx is great, the Enlarge vacuum was the THING i like it , 
i know its a relaxing satisfying game but i would like to see enemies or obstacles preventing me from discovering the ruins, but yeah in the end you got just 3 hours.
Nice them implementing  .

Really good music, also cool sound effect. very relaxing.  good controls. Similar "oxygen" mechanic, than my game for this jam. well done!

I enjoyed the game. Gives "Power Wash Simulator"-vibes. I don't even think it needs that many extra mechanics - just a cozy game like this is fine sometimes. I also had no issues with the audio.

The art is nice, graphics and sounds. 

However it's not really exciting, the digging is long and I did not have the excitement of finding the ruins. Perhaps with hintsto where to dig, and mobs making the digging uneasy, it would become more entertaining.

My face when playing:

Seriously tho, I really liked this game. Very cool concept and well executed good job!

You shouldn't be talking about the sound, it's not bad. Cool mechanics. But it is very delayed, then it gets boring to clean the sand, you will need to add activities, maybe sharks or something similar, and make the mechanics of cleaning the sand faster. The yellow submarine is cute. :З

It's so a quiet and patience game ! Love it ! your artwork is clean to create a minimalist and zen univers

Cute little cozy game concept!
It ended up being a little tedious to go back up to start vacuuming again, for each column.

Vacuuming from the side could be a great addition, maybe figuring out to do some Minecraft-esque sandblock dropping physics would make it feel very rewarding discovering ruins that way. 

Also the audio was fine for me, no issues!
