To be honest, that's pretty much how I rationalized it. There are a fair amount of bugs, and while I think the core physics is robust, I do concede that the menus, saving, structure, etc. are incomplete for sure. I got impatient with myself after having kept the development under wraps for so long, decided to yolo and, for better or for worse, show it off.
Note to self: Green Mushroom Plant Zone was a bad idea
As for level design, eighttailedfox built it incrementally as I put in more features and it suffers from flaws as a result. So it's my bad. Nevertheless, I'm sure he'd appreciate any specific criticisms.
As you may tell, I know my Sonic shit pretty well, even down to the code. If you are bothered by it not being basically 99+% accurate to the original, I can help you fix the issues. But I am not touching Unity with a long stick, so I can really only provide technical information and complaints about things you get wrong.
Again I disagree with the physics being that much off, but I imagine that working with the originals for so long the flaws would stick out like a sore thumb. It'd be amazing if you could help with the physics issues!
I'm a little salty. But any input is good input.
Overall I'm still glad I released. I've a list full of bugs to fix and things to improve, even if they probably should have been fixed before I posted. Thank you to everyone that's trying it out and giving feedback. I'll see what I can do in a week or two.
