Very cool entry and great use of the theme. I wouldn't change any gameplay, just add text popups to tell the player things like "press space" over the cage so they know how to drop items, "get to surface for more O2" (I had no idea you could refill O2 till I accidentally flew out of the water from going too fast lol). Nice work!

Hey I realy liked the music. I beleive it was really good match for the game. The dark levels added a how other part to the game. It was quite fun!

I liked the graphics and music a lot here! The chain physics on the submarine made me very careful with the movement and controls with picking up the treasure. The dark levels were fun. This game is clearly polished and glad you noted the bugs to improve on! Great job here!

Interesting design and nice terrain art. Its fun that my ship can jump from water)

The game is a lot of fun, the artstyle is interesting. I also like the sonar as a cool detail.

There isn't much to improve. I would perfect the system for losing treasures on collision and maybe tone down oxygen loss on impact since it can feel annoying from time to time (not too often). It would also be nice if it showed you some warning when the oxygen is low.

Overall, the game is great, polished and again a lot of fun.

Wow, I really enjoyed your game. I think if there was some 🐠 in background then it would look more sea like. although the chain was really fun.. and I flying is good . feels more fun to jump from one side of the ship and dive down to other side... the machines  was really good. Nice work.

you know a game is good when it has chain physics :D and that amount of movement freedom make me fly out of sky ... very fun game , keep it up :) 

(also plz check my game too;) )

i loovvee the radar animation. a littel information about what to do and what is the goal would be cool

This Game Is Really Unique.

I really liked the submarine player! Although I couldn't quite go any deeper 

I enjoyed playing this game a lot, especially how the controls were implemented, very smooth. I loved the graphics and the music was very catchy too. However I did break the game a little and got softlocked on the big ship leaving me to run out of oxygen but that was me just messing around with the game lol. Overall great game and you should be proud ^~^

I like the grapple arm. Very nice you made multiple levels,  i also liked the parts where it was dark and you have to rely on the radar.

nice game, love the music. However when I tried to go  from bot sea to the surface. the sub was nearly flying, add more force so that it couldn't be that high will be nice!

Nice game. You just need to better indicate what we need to do with treasures.

Nice game with great atmosphere! Well done.

Maybe one thing: Pixels have different sizes, which looks a little restless. Scaling the graphics / adding some pixels could do the trick.

I was pretty impressed by the sonar on the bottom right. Do you precalculate it or is it just a second camera with a shader?

Really cool game! I really like the music and the graphics. One thing that I struggled with was picking up the items. They would fall down quite easily. If you could make that easier, that would be cool. Really fun game, I enjoyed it!

I liked the sonar thing on bottom right. Biggest complain is that the controls are unwieldy

How did you do the sonar? It is insanely good! :D Well done. The deceleration is a bit... unique? xD But otherwise i think this is a great concept well executed.
