Wow! Thank you for a such detailed comment! I am glad someone likes my games and it powers me to continue focusing on developing this game so THANK YOU!
Yes, work is still in progress, with total of 4-5 chapters the game is planned to release on itch.io somewhere between October-November.
And yes, I am focusing on smooth gaming experience on low budget PCs (just like mine for developing games).
Ps. If Mistbourne will found its audience - will release it on Steam and other game stores by the end of this year.
