Ice Age avalanche is essentially the exact same game as Pastry Paradise in terms of gameplay, with the exception of having the Ice Age licence and thus having an ice theme instead of a cake theme.
The game is controlled entirely with mouse click with no extra assistance needed.
The cursor should probably be visible to make clicking easier. Dwell time is very arbitrary and depends entirely on the users preference, anywhere between 500-1500 ms should work.
300 – 1500 ms
