The sonar mechanic is super cool! Though i was kinda missing the steretypical "PING" sound.

It was pretty easy since after getting suprised once by the fast enemy i just super avoided them all. The map layout could have been litte more intresting.

I really liked getting suprised by environmental props that werent in sonar, really made the "exploring" more mystical.

Though the art is nice it little missmatches with the black sonar. The sea near you is wibrant but then there is completle darkness in sonar area. Either having the sonar be a lighter color (maybe even inverted so the ping borders are black etc) or having the sea be more dark. Now those 2 concepts fight eacheother, am i diving into a nice colorfull colar or a deep dark depths?

Would love to see this as more full game!

Nice concept here, but you really need to make the player hurtbox smaller as I died multiple times without even touching rocks/jellyfish

Wonderful Game! Somehow difficult for me, though. Perhaps making the sonar last longer, or have a shorter cooldown would be better?

Nice game! The sonar mechanic is definitely my favourite bit, maybe adding a recharge bar and sound when you use it could make it feel a bit jucier?

Super cool game! The music is killing it! Sonar is definitely the best part!It's a bit difficult for me thou;;I think it would be be better if the vision area is bigger? But otherwise really nice job!

The sonar mechanic was a pretty cool idea!
Maybe I messed it, but having some way to know when the cooldown is ready for it would have been a nice addition. Also playing full screen as mentioned in the page's description made the energy bar cover the character, so I had to play on regular size screen, but it didn't bother me.
Awesome job overall!

Interesting idea, it would be great to have a little more information to the player about what is happening, for example charging the flashlight, sometimes it is not exactly what you crashed into. Cool idea, can be developed

Nice game! As everybody said I also like the sonar :)
Maybe I would scale the vision with a bigger circle gradient, gg !

Cool chill game :) at first i thougt it was a bit hard but then read about sonar it was then much easier and I could reach the bottom :) Music is nice, it was a bit hard to enjoy all pixelart because of darkness, maybe it could be cool to have a little bit of light around with the sonar ?

Good job !

I like the general idea of the sonar (and the visual effect), though, maybe I'm missing something, but since there isn't any way that it shows the cooldown, and there isn't any penalty to spamming the mousebutton, I found the easiest way to play was to do just that.

(Oh, and I had to start the version on the itch website, the version here is either bugged, or otherwise the support isn't there yet; even if I press the full-screen button, there's a huge blue area overlapping my view...)

Very nice. Having a cooldown indicator for the sonar would have been a great addition.
