I liked the take on controlling two objects at once, and where in many of the other games it would take me a while to get to terms (or never get to terms) with controlling two objects, in your game it felt very natural right from the start.

I did have a little trouble making use of the cannon, and I think this was a combination of it being a parabolic arc and altering where it was aimed as I moved forward and backwards (or maybe I just didn't ever understand how to aim it) so I ended up relying entirely on the sub's torpedoes for damage. 
I got confused as to how to eliminate the barrage of incoming fire that appears from below the map - and that ended up killing my sub and ending all my attempts at progress.

This was a great idea and I loved playing it for the most part. I just had a little trouble with  the enemies popping up off screen and I wasn't able to hit them. The ships also did desync at one point which made it a little tricky.

I love the concept, and the controls felt responsive, although I had trouble hitting things with the right click attack.  It did seem to ramp up pretty quickly though, and even before the giant wave I was being bombarded by enemies that were off-screen and out of reach.  Except for that aspect, I had a good time!

A solid base for an interesting shoot'em up. Did run into a bug that caused the ships to desync from each other making the bottom ship only able to move up and down not too sure what the cause was though seemed to only happen when I wasn't in full screen. Also had a bit of flickering with parts of the background textures.

I think if given some more time and polish this could be a very fun game. Great work, keep it up!

Very satisfying shooting audio :) I couldn't make it past the wall of enemies, there were too many! I tried aiming the submarine torpedoes with my mouse but they were only going straight ahead, not sure if this is a bug or not?

GJ on the Jam!

Nice take on bullet hell and mirroring! It's cool that you two sides have different mechanics for movement and firing. The most annoying, though, was that some enemies were below what you could see, and they kept firing even after you long passed them.

I also liked how the reversed boat looked a bit like a blue whale :D

Interesting seeing a Bullet hell game like this, but I wasn‘t sure what the boat on top was for, neither did the controls get explained. I think it has potential but needs some more polish and work. Overall, good idea and if you don‘t give it up, it has potential.

I kept spamming the control and shift key and my computer kept interrupting me to check if my key was stuck, lol.

Fun idea! I'll say there might be too many enemies too quickly. But that could just be me being bad at shooting games.

Great twist on the bullet hell genre :) At first, I was puzzled why the top vessel wasn’t mirroring my movement along the Y-axis. Then it hit me. I’m controlling a boat on the water surface. I had fun :D

When I got to that first giant wave of enemies, it felt impossible to proceed. Still, it's a fun idea and it's fun to fire a bunch of missiles and torpedoes at enemies. Nice work, congrats on the submission!
