I remember playing the earlier version. Unfortunately, I played it at work last time, as did I this time, meaning I didn't have the time to get into what feels like a fairly slow game, so I can't really provide any "fair" feedback, but:
The polish bits feel really nice, like showing the controls and introducing new features in a fairly logical way, without holding the players hand TOO much.
The cross fading backgrounds are kinda annoying, imo.
Even though the graphics isn't technically perfect, they are consistent and clear, and fit the game really well.
I didn't find the controls annoying, except for the game being a bit slow. I would have preferred faster movement, but the inability to jump didn't bother me since the level design seemed to have this in mind.
