I hadn't tried Einstein before seeing this forum thread. Tried it on the desktop version, looks fun. Thought I'd also install the NIT version as well.
I don't know if its possible, but a zoom function would be nice. Trying to choose what character shows up in each box requires some delicate clicking. One wrong move or slightly uncalibrated screen can end the game. Or, instead of zoom, if the size of the game area was increased and the size of the hint area was reduced it would work better.
