First of all, congratulations on the first test build! Overall it's been a nice experience trying it out and some of the views outside are absolutely gorgeous, but as requested here are an assorted list of problems, things I've noticed and suggestions.
Specs: Windows 10, Intel i7 920, 6 GB ram, Nvidia GTX 560
1. The mouse feels sluggish. The experience can be compared to how some games have mouse smoothing, which when enabled also makes it feel sluggish. Like a small delay on your mouse movement.
2. Pressing the load button in the main menu with nothing to load (taking you to the load screen) makes the game essentially lock, since you can't get out of there. At least I couldn't figure out a way to do it. Esc didn't work, pressing cancel does nothing etc.
3. I can not recognize the song in the first dungeon. If it's the correct song, then the midi library must have made it sound weird.
4. The sky outside makes me dizzy when moving. It's that it moves differently than the ground. I know Lucius (DaggerXL) fixed this by using some kind of cylinder around the world and applying the sky texture to that (if I recall correctly). I think having that sky texture is really nice though and it blends good with the horizon.
5. Z is a unintuitive default choice for ready weapon. If it's like that in vanilla then sure ok, but from Morrowind on it's been F.
6. I want to be able to rebind quicksave and quickload since I usally have F9 as quickload and I accidentally keep saving when trying to load.
7. Trying to load an old save outside in the nearby town makes me fall under the ground to the nether. Attached the save.
8. Would like a god mode button or code and a super speed button or code.
