Until now，I have finished the collisions of my player，enemies and the bullets.I made a debug function to draw those collisions.It's looks good.
Now，it is actually a game which can play by someone else.But it has only one enemy，no skills，almost no animation，no plot，no goal，no score.It is not fun at all.
That's what i want to do next.I want to make it more like a roguelike game which like Brotato or Vampire Survivors.
This type is a litte flooded. But it is suitable for a little STG game. I actually have some ideas，I hope it will be
fun，
