Pretty impressive for a Scratch game! I actually started game development on Scratch as well. You're definitely very skilled, so I think you could really excel if you wanted to use a more advanced engine. Taking the leap can be a little daunting, but it's really not as bad once you go for it. A possible starting point would be Pico 8, which is super beginner-friendly, and there are a lot of good tutorials and documentation. There's also both a free and paid version, so you can try out the free web version for a little and decide how you feel before fully committing to it. (Very subtly indoctrinating another Pico 8-er.)
Edit: Of course, if you want to keep using Scratch for now, I won't try to convince you otherwise, I know of some creators that have done really amazing things using it.
