I loved how relaxing this game was and how fitting it was to the depth theme, however, I don't think it really met the limitation. I loved the creature designs and how unique they were to the environment. oddly, reminded me of slender: the eight pages just a lot calmer.
a few gripes I have with the game is how the water looks, I feel like throwing in some particles and effects would convey the feeling of being underwater a lot better than how it's done here. Another thing is the movement, movement isn't really important in these types of games, however, the movement did feel really clunky and slow and made the pacing a bit strange during the playthrough.
but all in all, this game is good, and with a bit of polishing it could be something amazing.
