Excellent graphics, but the UI needs some work. Long compulsory delays on some text (why? Sitting there spamming the mouse/spacebar desperately waiting for your game to stop blocking input ... isn't fun), and something broken with the mouse sensitivity (I have to move the mouse 10x across the table to move across the screen, only with this game. Something broken in your mouse handler in Windows?). Eventually too annoying having to constantly move the mouse, wait for delays, etc.
I'm not aware of the issue you mention, the mouse sensitivity is normal for me and I haven't had anyone else report it being lower. The "compulsory delays" are also most likely a technical glitch that shouldn't occur for most players. Do other AGS games work normally for you?
Edit: on second thought, there are three short paragraphs at the very beginning of the game which are part of the intro and are unskippable (each of them appears for roughly 4 - 5 seconds). Maybe you meant those? They will be skippable in the full version.
