Very nice idea. reminds me a bit on Sea Of Thieves. Unfortunately it was barely playable for me The mouse is not locked to the window and I kept losing my mouse focus, because my mouse dropped over to the second screen.

Also, the game felt very slow. You could increase the speed and add some more action to it. 

Great job on the game. I can definitely see the effort put into it. The mechanic is interesting and relevant to the theme. I did make it through the first level, but gave up after getting stopped by the wall behind the goal.

Here's my feedback:

• Textbox is hard to see. Maybe it's a resolution issue, maybe not, but I did not notice the instruction popup and don't know what to do until a few minutes into the game.
• Ship steers weirdly. From how I felt, the rotation of the ship seems to be fixed instead of its direction or maybe it's because the ship is stuck to the wall.
• Ship tend to get stuck on walls. Whenever my ship touches a wall, it gets stuck there forever.
• Planks can be connected to player. I don't think this is an intended feature because the player moves slowly when a plank is connected to it.
• Lack of audio.

Great job submitting the game!

It's a cool concept, but it is very slow until you win, and it's very buggy with that I loose all my items at like the first second of a level.
