I agree with you on the points of story, riddles etc. but when I saw games that were made by Visionaire for the first time I was instantly let down by the stiff animation system. Characters not turning before moving, no acceleration or deceleration in their movement, just sheets of image sequences stiffly sliding in different directions on a background image. Those small but effective details are there for a reason, to give the characters and other objects a sense of depth and immersion, and blend them better with the backgrounds.
But, hey, it's nice that you guys are making it possible. The more options there are the better.
