I don't think it's hate; the games market was oversaturated before AI, and it's even more saturated with it. Players have limited time and patience that usually doesn't work out in-favor of indies.
Making the game that OP made, a basic Simon-type color matching game, isn't that difficult. None of the vibe-coded games I've seen posted to HN would be difficult to make in any engine. If that or any other such game had been written by a human being and posted here it would be getting a similar reaction because none of them are any good on their own merits.
But because they're AI, and only because they're AI, people gas these things up regardless of quality, almost in spite of it. That's why people are mad. Not because they're "haters" but because people are flooding HN and the rest of the web with slop and insisting on being treated like masters of their craft.
And again, if a human had written this game in its entirety and posted it here, it would get flagged as spam, because it is first and foremost a bad game. Even as a "beta." And OP can't improve on it much because they're limited by whatever the AI happens to generate. Even just giving them encouragement is pointless.
"Games are impossible without AI" is a paltry excuse. My nephew, who isn't even in high school, is learning coding in school and is making games in Roblox. It's never been easier. If it's true that making a game in AI takes actual skill and work, as people claim, then making it in an engine is not at all beyond anyone's grasp.
If y'all want to shut up the "haters," make something with AI that's actually good, a game with a coherent visual look, well designed gameplay, an interesting concept, that's at least as good as a tutorial project for any existing game engine.
The "able to make the X" thing is something haters love to ignore.
Best of luck with your beta!
