Completed this in about 15 mins or so.
Its a fun, albeit short experience. The art on the squid at the end is awesome, and its a nice little end to meet your mom :)
Cool job on the art overall.
The gameplay wasn't hugely gripping for me personally, but the sonar ability was pretty cool. I would say there was a bit of a mismatch between the art of all animals in the game, but overall, its a fun little experience.
It was challenging in places, and fairly easy overall given the intentionally slow and sombre nature of the game.
You should be proud of what you made. Nice job.
