Thanks for the feedback!
I’ll definitely add a windowed mode option in the next update — that should help with the fullscreen graphics issues.
As for getting stuck on “Input Complete,” what’s happening there is the game is loading the full character customization scene, which currently includes a lot of high-res (8K) textures. It’s a pretty heavy load, so performance can take a hit depending on your hardware.
I’m planning to downscale the textures to 4K in the next build, which should make the load time and performance 2–3x faster. That said, getting 2 FPS even in the menu is definitely a red flag, which aroused my curiosity.
