The game over screen made me jump out of my seat! Really liked the mechanic that the barrels were moving as well! Really enjoyed the sound effects (ambient and active).

Once comment I would mention is that  if I dropped a cube while moving, it would sink like a stone straight down rather than in an arc off to the side - I don't know if this was intentional, but personally it stuck out as an inconsistency in the game's physics.

I love control of the ship, really god game, well done ! Good Visual too
