A little more work from good towards the great
I loved the music, who is author of it? The gamestyle was well in the steampunk genre, which is all the rage now, I like it too. On graphics - why the proferssor has no hands? I imagine it'd be a bit difficult for him to live without them. Also, the movements where a bit too slow, a little faster next time. The puzzles where way too easy - i didn't need the hints on the board to solve the code lock, more challenge (but no pixelhunting, please). Loved the jokes of fnord and drugstore - so makings of decent plot - don't ruin it, spending extra hours on plot is worth more than extra hours on making something prettier. Overall - good work, I expect the next part to be more polished and longer. This could be the making of great series!
