Thanks for your comments- glad you had fun!
We have actually given in to popular demand and added hotspots to the next build of the game. This will be uploaded soon (we've also fixed the Wrong Un bug).
We haven't given in to demand with the puzzles yet, though! I think these are hard but fair ;)
I'll keep you posted on the full version. This could be some time off but we do have the main coding elements and most of the story done now.
