Easy to understand interface. Two views: today and (custom date). Lots of cities at a glance. Visual reminder of day and night :-) Export to clipboard is great - would be a time saver if could export directly via Share to email. On tablet, would love to see wasted space on right side used for big font for day & time. Bonus points if you'd give visual reminder of "day before/after the custom date" ! (so I notice that my Tues is their Mon :-) And free? I'd pay.

When the high scoring solution for almost every level is "one bird" the puzzle aspect of it disappears :-( Not enough variety, not challenging enough.

Waaay too long a delay between original game and update (which contains verv few levels). Ads are a bit annoying and price asked for removing them seems to me too high. Too bad, 'cause game itself is genius.
