I never got a "Nero" recognition while testing (if I did, I would have forced the game to accept that too). I suppose the many different things it can recognize based on your accent is just one additional barrier you have to overcome for an actual good voice recognition game.
The narrative independently developed out of the basic gameplay.

I don't seem to be the only developer with bold game content :)
But this lack of accessibility is probably why you see it so rarely in gaming. It's not that difficult to set up a (scuffed) voice recognition. Even simple games using your microphone seem to be positively received though (based on my memory). This might also just be bias.

The poor little AI model is only 67.6 MB - so it doesn't work well. In retrospect, there were multiple ways I could have mitigated the problem, but I also had to make a game at the same time. Thanks for calling it interesting!

Just to be sure: You got past the first screen and didn't consider it enough of a game, right?
Because I just realized it's possible to see the first screen as a troll that does nothing.
Thank you anyway for making me think of that, I added a new game screenshot.
