CROS here from Game Jolt. Just wanted to let everyone know that we've launched our achievements system in closed beta. We're looking for interested devs that would be willing to help us test out the system and what not. The goal is to create the best stinkin' achievements system out there that works with as many platforms as possible while still being extremely easy to use.
The good news? Construct is taken care of, and is a supported platform. A nice little plugin is all ready for testing.
We hope to keep the closed beta period short, so that we can get more devs using it right away.
Here's some more information on the system, and how to sign up for the closed beta:http://gamejolt.com/developers/achievements/
Let me know what you guys think.
