generic space shooter (test)

Hello! This is a test from me as a novice game creator, the game is a generic space shooter (I did it in 2 hours) and you have to get 1000 points, and you start with 100, to get the 1000 points you have to kill the ships that will be generated every 2 seconds and prevents them from accumulating or it will be more difficult, if a bullet from them collides with you you lose points, if your points reach 0, it means that you lost and the game will close, and that's it, I'm open to criticism all types
