I really enjoyed this! I do have the "sticky keys" shortcut disabled on my computer, so I didn't experience the issue other people were talking about. The music works very well, movement feels good, I like the leveling system, and I like the fun gadgets.
It took me a while, but I figured out that the quest objectives are numbered incorrectly in the "revenge" campaign, as it counts the tutorial stage as the "first" stage. Maybe re-number those quests accordingly so it's less confusing.
Edit: I'd change my rating to 5 stars if there was a plot. I haven't moved to the second campaign yet so I will keep it in mind as I continue.
