I really like the concept and 3D models, they're quite good. But the boat is SO out of control that it's almost impossible to keep more than a handful of boxes aboard. Also I didn't know I had to press Enter after placing the cargo and sat there for awhile... but I had fun anyway! Good submission!
Also just a side note: I think you should use a better thumbnail picture. An in-game screenshot of your nicely modeled and textured crates sliding around will give people a much better idea what your game is, I was pretty hesitant to play at first b/c the picture looked lame 😅.
