The intro cutscene was really cool! I did have a few issues however. There seems to be no way to die, I even stood right in front of one of the Metapods and it just pushed me off the platform, at which point I realised there is no gravity and you can just walk off screen.
I would also recommend finding more royalty-free assets rather than ripping Pokemon models, there are tons of resources like Sketchfab and Kenney for this.
Don't be discouraged though, I can see you're still quite early on in your gamedev journey. Keep at it!
