I'm sorry for the reversed controls. I probably haven't played enough point and click games recently, and when I tested my game at first with the default controls (which are as you described), I was confusing them every time, so I decided to change them because it made more sense to me.
I should have listened to my testers who told me they were a bit confused by the controls... it's totally my bad on this :S
Just for future reference, if I work with this art style again, which items, if you remember, did you find unrecognizable without their description? :)
