Good job on releasing your first build! If I can give any advice, I'd recommend looking into reducing the file size of the project. 850 MB is insanely large for a first release! You can bring that down a lot by converting your sprites from png to webp, as well as using layeredimages instead of having a bunch of full-body sprites. You should also consider removing unused backgrounds and audio tracks to try and trim the fat a bit.
Other than that, this looks very promising! Wishing you good luck!
