I have played games made before 2016 that were very good.
No reason to think that this SHOULD be bad due to it being made 4 years ago.
I would also say: you've figured out how to make a "working" game, and you've figured out how to upload it, and share it with others.
This is a bunch of steps forward, and you should keep going.
If you don't want to improve this one, go ahead and do something that interests you now.
This is like a proof of concept, now "make the real thing".
