This is a pretty minor change gameplay-wise, as minor as it can get probably, but still.

In the game reptile roundup controls are much easier to use on pc and as far as I know you have to manually click the "play again" and "start playing" button. The two aren't on the same place and it can be slightly aggravating due to the layout, it'd be easier if both buttons overlaped since you only really use the directional keys to play.
