Okay, a little update from my end. I'm in contact with a game developer as well as learning the capabilities of buying code for a game and changing it myself. I'm continuing on full speed ahead on the front-end side, have multiple websites in planning and development (things like a blog site for sending out news and a site that serves as a hub that links to reputable 1CR mining pools).
We're going to plan a rough-draft roadmap and see how the community likes it and discuss/debate what improvements can be made.
We should have a fully playable game within 2-3 weeks, probably sooner rather than later. It won't be able to pay out 1CR until the blockchain is fixed, so that has to be a priority.
I think we should hardfork (or hire someone who can do that for us) so that the coins from the attacker are rendered useless. After that, we'll have a strong blockchain with many miners making it too difficult to attack.
Is there anyone here who can take over the back-end work of stabilizing the blockchain?
