Starting a few weeks ago, our lead 3d artist, turjuque, stepped up into the lead coder role as well and revamped the gameplay codebase,
so it's now coded better and actively developed (there are still a few regressions though for now).
Gameplay is constantly updated and includes more and more functionality and polishing. It's still far away from a proper game, but version 0.1 is due in about a month.
Would be nice if more webcoders and such would contribute, here is the repository https://github.com/FreezingMoon/AncientBeast
And ofc, the pre-alpha itself which is publicly accessible and somewhat playable atm http://AncientBeast.com/combat
Keep in mind it's developer preview, rather glitchy and very limited atm. It will shape up and probably become private-alpha within a few months.
