Great job dude, i was able to clear the tutorial without problems, really help me to understand Superpowers' and Typescript logic. also, i made a few improvements on the game, (integrated different musics and sound fx, added a modifier on the missiles that allow it to rotate the model as the same eulerZ that the caster and a shield for the ships when it's invulnerable) planning on setup a kind of power ups when asteroids are destroyed that allow the player to modify the shoot pattern. If you wish can check my work here space-war, thx for the contribution.
