Hi, this sounds very interesting. I'd consider it as an indie dev if the DRM stuff weren't there, IMO any injectable DRM stuff is going to cause more problems than it solves, and piracy is not a huge concern anyways (it's "crappy free marketing"). Also "not changing the source code" isn't really a big selling point, if a indie dev is going to release on a new platform, making a specific build for it is not a big task. Big platforms like Steam don't require any DRM, the developer can of course still add their own.

The other problem that "pay-for-playtime" has shown to have on Apple Arcade and similar is that it penalizes "content rich" games where the player can play through rich, authored content in ten or twenty hours and instead rewards more endless mode game. Not that there's anything wrong with those types of games but this means that eventually, more meaningful games will be driven off the platform and it will be just idle games, puzzle games and farming simulators. I love those kind of games but it can make the platform feel cheap. I think a pay-per-install metric would work out a lot better in the long run for you.

I'll keep an eye on this service, definitely the more outlets an indie has the better.
