To be honest your game is good if it's good enough to make you enough money for living, i don't know. In my opinion you should first really think about quitting your job. I'm not saying you don't have a right to feel miserable there. So maybe just think about if it's always been that way and if there isa possibility to go back. otherwise maybe look for other job opportunities that could interest you more. If you really want to become an indie game dev that's for you to decide.
It's been this way for a while, that's why I've been trying to save up as much as I can for at least 2 years now. I know just willy nilly go fuck it I'm gonna quit my job and made my game and make an easy living is a fairy tale, but also I feel like not taking a shot at it to really know it's not possible is doing myself a disservice.
Thank you for your point of view, I will consider everything as carefully as possible before making a decision
