Switch away from Games to WebApps (mini-apps)

[gabeklavans]

The Games platform seems to have been a bit abandoned in favor of WebApps, which is basically a better API in every single way. By better, I mean it can do way more (like give haptic feedback!!!!!) while still accomplishing everything that a Game can do. Certain things just require more manual effort, such as score tracking and the branding (like the gif in the message).

I've already invested heavily into (read: abused) the Games API, so I'll keep it for 1.0, but with the promise of much cooler integrations with Telegram in the future when this switch happens.
