Unfortunately, this game is pretty bad. The concept is actually quite good, but unfortunately there are many annoying factors and bugs.
One annoying factor is that the surrounding islands, which are very close together, destroy the ship immediately upon contact.
The controls are unfortunately very poor; when you reverse, the hull moves very quickly when turning, which means you quickly end up in a collision and the game is over.
Then you can only change the weapon using the number keys, which I find too slow in some situations.
The weapons can also only be fired by double-clicking.
Another thing I noticed is that you can buy a new ship even if you haven't collected enough coins. You'll be in the red, but the next time you start the game, you'll be back to zero and can buy the next ship with just one coin.
