With 79 votes the winner is PAN!, followed by U-91306 Eidothea with 76 votes. The third place, grabbing 72 votes, was Edge of Time.
I shot three short videos of the gameplay of all three games:

In my personal opinion, Edge of Time is better than U-91306 because of the dual-screen concept and graphics. PAN! is clearly the rightful winner for its interesting cartoony graphics and arcade style. Nonetheless all three games present great quality making the Commodore 64 enthusiasts the real winners here!
