After attaining all the medals in the first Bird Hop game this was much easier, I got 2500m at first attempt with the basic bird which unlocked all the birds and then exceeding 10000m in the next day with multiple special birds.
Most obstacles from the first game are also here but some are changed. The crushers are substituted with red flying non-bird things. The good thing they are slower, less long or wide, which makes them easier to pass and thus makes higher climbs easier. The bad thing that it is impossible to understand what they are and that the crushers are removed completely, I think that some crushers should be left, just made very rare. They could start appearing only after 5000m and be very rare, like once or sometimes twice straight after each other for every 1000m, so that there would still be some hard places. The same can be said about spiked ceilings, some of them could have been left for the diversity of obstacles, just made more rare.
The best and most fun new obstacle is the other birds, unlike other obstacles they are not lethal, but they sure do have potential create a lot of chaos and confusion that can be dangerous, although sometimes it can play to players favor by triggering the shooters (which again can be either beneficial or bad depending on timing). The unpredictability and ambigiousness of these birds make them the most interesting thing to encounter on the climb up.
Still ,the best improvement over the first part is that the different unlockable birds (and a non-bird) are different not only by their looks, but also each has a different ability. Most abilities are a mixed blessing, sometimes useful and sometimes dangerous, which adds some more depth to the birds that have them. Some unlockable birds are stronger then the basic bird while others are more harder to play. It is mainly because of these different characters, that I rate this game a half-star higher then the first game.
I am not giving all 5 stars because of some minor issues. The first game had a small intro which told a small but still nice story, this game abandoned that. And also the custom bird selection does not work. And as I already mentioned I would have liked if all the traps from previous game made appearance in this sequel too an d game difficulty would be regulated by their rarity rather then absence. 4.5 stars is still a good score trough.
As I write this I am on approximately 150th attempt and have reached over 10000m with three different birds and one of these climbs is second best in global rankings. All medals are attained except the one where you must die 300 times. I will try to get over 10000 meters with as many different other birds as I can until hitting 300th attempt and getting the last medal and then it is time to put this game to rest.
