@replay/text-input v0.11.0
Replay is a cross-platform JavaScript game engine inspired by React.
Its declarative API goes against the grain of typical game engines. It's small yet powerful, giving you total control on how your game runs. With a great testing library built in, Replay is ideal for writing bug-free games.
Build your game once and deploy it for web or iOS (with more platforms like Android coming in the future).

⚠️ Status
Replay is still in early development and will go through many breaking changes. However we encourage you to start making games now - your feedback will help shape Replay's future!
