I really enjoyed the simple, but effective graphics. The music was beautiful, and it would be great if there was more "symphony" type music one could choose from. There are a lot of games out there similar to this though, so you may want to implement something different that makes you stand out from the others. Ex: Planets have certain upgrades (atk, def, speed ect). Something like that. I would still suggest to keep it simple, but definitely add that edge. :)
Would be nice to know the levels of each city. I went from one city to another city where my top boat was 150 health. The city I went into had 300 hp each and I got DESTROYED. Panama is dangerous... But yeah, level of city would be nice! Thanks and great game! 5/5
Improved a ton of options and things that were lacking or misplaced in your first game. The whole training system and upgrading system was flawless too. You all efficiently fixed the game to make a 5 star game, in my honest opinion. One thing I would do though, is warn the player that if they fight the king and win, they will end the game. If I had known that, I would have decided to fight the dragon and kill that first, considering it was so powerful. Over all though, fantastic sequel of a game. 5/5
