Thats a serious amount of work you have put in it! Really looking forward to the launch, once it is out ill give it a go for sure.
About the how to /if a user can get hyper from playing (maybe it is possible to talk to OP and ask what he thinks about it, and how it could work). Could be something like you can trade ingame cash for hyper, or items (similar to what happened on Rust)
