I just love scratch, you can get so creative with it. As Noon said, go on and try an actual Game Engine, you WILL have fun. I recommend Godot as I think it has the lowest learning curve and is still simple enough, but just try out some stuff based on YouTube tutorials and see what you like.

Regarding the game: the control is a little clumsy so it is hard to judge. I just think you reached the limits of Scratch regarding performance for games on the action side.

The fact that you made this on scratch is actually really amazing. I hope you consider using Unity or Godot in some of your future projects :) I can tell you can do real well! Hope you start feeling better :)
