The roadmap is currently focused on adding a brand new zone called "The Collective Mothership." We are working on art assets for the zone including Battle Sprites, On Map Events, and Game Overs so it is a fairly ambitious next milestone goal. There has also been work to continue the side events involving Succ or Bust and additional events at the Khrono Manor.
Much of the art progress can be seen on the Art Twitter.
Thanks for the kind words! Summer has been a bit busier with other obligations popping up as this is a hobby project but work is still continuing.
