Thanks for playing and the feedback.
There are shortcut keys you can hold while clicking an action to skip the additional selection steps. For example, if you hold Shift while clicking on an action, it will skip the Select Target step and use the currently selected one. We are working on redoing the tutorial to just show useful tips like that, or find a better way to slip them in. We also are looking at options so you can set the default, and the key press would reverse it. We can't remove the ability to select your target manually, as it does have more value later in the game. We will look into other ways to perhaps simplify this process when you don't want to see the extra steps.
The dialog boxes being a larger size fits the style for a story heavy game like this. We do have plans to add sounds for the dialog boxes. We started to add it, but the sound we had chosen didn't work out once we tested in game, so we need to go back and find something else.
