This was fun! I like the aesthetics. Great feel of discovery! The unconventional controls take some time to make sense of a bit more to get a good grasp but feel really satisfying when you do! Could be a really cool sea adventure game
Some weak spots I've met: - camera angle drastically limits your view towards south - once I first heard a tentacle and only then I saw it lol - there are shallow land patches which totally looked like shortcuts when submerged, but they were not -_- And this is how I lost the first time hahaha - the knockback force from crashing the land seems to be a bit too strong, feeling of loosing control of your ship is a bad feeling, I'd suggest nerfing that by some degree
Other than that, great job!
