I think It's A pretty cool game. So it's Good(as for my opinion)!
(but good have different gradation, If "good" means pro level or market success, then I'm not best adviser)
But If You think that gameplay feel not enough for You as Author. Then, shure thing, practice and research always levels up, give opportunity to improve and You'll get what You want. We always need to grow :)
If You interested? I can make detailed review of every game aspect , with what I think about every part.
(when found time)(DISCLAIMER: I'm not pro gamedev, gamer or journalist, just random person)
Wish You to become as good as You want and All the Best!
