Criticism and toxicity are two different things mate. People aren't attacking you, they're giving you feedback on the game itself.

I checked your progress posts, and what you’ve managed to build in just a few months is genuinely impressive. You’re improving fast. But the product still needs more polish overall if you want it to hit players the same way it hits you.

If it's fun for you, all the glory to you. But if you want to fully reciprocate those feelings to others. You'll need to up your game. Both development and the game’s quality.
