I was repulsed too at first, but honestly cheap build-your-own-video-game tools have been out there since the 90s at least. This is just the modern version. Fine.

I could see microgames creep into social media feeds maybe. That's what this allows for. Games that might be novel for a few minutes. Some folks will put in the effort to make a modern multi-hour game here but very few, like their player-base.

Also, prototyping! Maybe it's good for that (just don't share it publicly).
