It was 5 stars then 3 and now 2. There have been NUMEROUS occasions where blocks are falling and JUST about to kill the last pig, then the level fails me even though I was about to win. It needs to wait until the bird disappears, because now it's failed me 5 times now, causing me to lose out on varies prizes. Also, the arena matchmaking is a joke. Pairs you with people you can easily beat, then for DAYS, pairs you against people that are way higher level than you, so you can't progress levels.
