I don't think you can really fail to "try" to improve if you're still producing games. There are those who might not put as much effort in, but anyone who's still going is always improving in some aspect.
Just keep at it regardless of what anyone else thinks or says. You are improving at SOMETHING whether you think so or not, so long as you just keep going.
If you're really that concerned about things in your games being "wrong," maybe do a review swap or something with someone: you review their game, they review yours.
Don't beat yourself up. Anyone who's trying and failing is already ten times better than someone who didn't try at all.
