That's bad though, why would I have to click a button that does nothing (the player can see) before being able to click the enemy? As far as the player is concerned, the game is already in attack mode, with the mouse cursor being the interact hand.
Also, moving to the enemy and back and watching their attacks takes way too long. If I hadn't finished the rat with the third attack I'd probably have Alt-Xed out again...
I admittedly don't have any patience for things like that, but it's still a bit tedious. Stuff like that, especially stuff that repetitive, must be really fast or possible to skip.
Excuse the harshness of my comments, but I think that gameplay flaws such as those must be ironed out from the start, ideally during the alpha test
