I'm surprised this hasn't been mentioned yet, but the game has hidden camera controls that let you change views in H-Scenes. Pressing +/- or the number keys will let you cycle through various angles while in H, and spacebar lets you skip the scene entirely.
Also, by messing around in the launch options you're able to play in fullscreen and increase the game res. You can do this by right clicking on estras.exe and creating a shortcut, then going to "Target" and pasting this after the original text (filling in the numbers with your monitor res):
Code:
-screen-width 1920 -screen-height 1080
Note that this will tank your fps if you're on 0.0.3 and the UI will look a bit weird, but the game will look much cleaner now.
