Since you’re reading this site, means that we’re very close to releasing a decent alpha with plenty of flexibility for creating 2D games. If you have signed up for a beta key, you will have access to the alpha.
Next steps are to continuously add new features and fix bugs as they come up. Two of the major features are 3D capabilities and multiplayer and once we have them, Spark will be in beta. We do not have a set date for beta, as features become available those who have access to the alpha will have access to them.
To those who have been waiting for a while for your keys, thanks for your patience and for sticking by us this whole time.
