Hi!
Just tested your game and managed to win it on third attempt! It's nice little space shooter, although I did not quite get how the theme "magnetic" is used in the game. Are you still developing the game further and planning add some new features or did I just completely miss the part? Also, if you are still working on with the game, I hope it also gets a scoring system! (And I think that is also a requirement for this jam.) If you don't have any ideas for the scoring you could use even just a really simple score system like giving 10 points each time a bullet hits an asteroid and then displaying the total score in left or right upper corner. That would already add a lot to the competitive aspect of the game.
