1) Audio with headphones is painful since left side stuff is purely out of the left side. This makes sense for stereo speakers, but not for headphones. 2) To measure the distance the mouse has traveled then recenter the mouse to the center of the screen severely alters how the user's natural mouse settings works. This cause the mouse sensitivity in game for me to be dramatically higher. You are not a First Person Shooter. Don't act like one. Use a normal mouse as it is intended to be used. If you wish to screw it the mouse sensitivity, provide a mouse sensitivity option within game. 3) You are not an IPad game in Steam. You are a PC game. Act like it. There is an entire wasted keyboard waiting for commands. Starting each of the unit types building could be done by numbers, or perhaps provide a shortcut key for each of the units. Spell casting is annoying without shortcut keys. If these kind of keys are available, they weren't marked on the screen as such.
