Hi! Thanks for checking it out!
For what it's worth, ハイグレSim has been put on the backburner in favor of my other haigure-related projects, but my latest goal is to port everything from the Unity Engine into the Unreal Engine. After that, I will work on refining the NPC AI so that they flee properly from both enemy NPCs and the player if they have been converted. Alongside that, I'd like to get the city's visuals updated and re-arranged to fit the manga the setting is based on.
If you are interested in haigure at all, we have a Discord server which can be found at: tinyurl.com/worldofhaigure
Or, I post updates on most of my projects monthly (including ハイグレSim) on my FANBOX, which is: trishdev2.fanbox.cc
Otherwise, thanks for your interest! Hope to see you around!
