I like the concept of having to use both hands to control two things on the screen! I can see a lot of thought went into this, with a variety of pickups and ship types, etc.
However, some things stop me being able to enjoy the game to its full potential. I got lost on what was happening sometimes. My right tentacle ended up looking like a black spot and I didn't know why or how to restore it. Also, I cannot tell what the orange and green bars are for, unless I read the game's page.
Once my left tentacle ends up on the right side of the screen and vice-versa, they become hard to control. Could you maybe add an L and R on them, or find a different solution?
If you add more visual and audio feedback to help differentiate what is a good thing (pick-ups) and what is a bad thing it will help. Also, instead of colour-coding them, I would change the design to explain organically what they do. For example, the antifreeze barrel could have a label with a snowflake in a shield, the speed boost one could have a double forward arrow, etc...
Another thing: can you actually destroy and wreck the ships? I am a kraken, terror of the sea, I want to be able to wreck havoc! A good amount of destruction on screen with matching sound effects would make the game even more enjoyable in my opinion.
Overall, a very good foundation for a cool game. Serious work here.
