Seems like you’re making steady progress. I tested the game after a long time, and will come back when I have time to play it properly. At least the menu music is now stuck in my ears.
It will be interesting to hear about your experiences on Unreal. I’ve been thinking of trying it, but also I have to upgrade my computer first. Simultaneously running Unity, Visual Studio, Blender, Substance, Gimp, dozens of Chrome tabs and various other things is quite a load for hardware, and judging from the noise my GPU makes, it cannot take it much longer.
