When I saw that it was made in Unreal I was like; yep, that explains the 'technical issues and setbacks.'
Was this your first time making a game in Unreal? I haven't had the courage yet XD
I used to be a Unity guy, but I swapped to Godot since they're supporting 3D more and more. The workflow is faster in my experience.
Gave you a follow. Hope to see it finished!
