tip to new players: try to upgrade and unlock as many units as you can and get the equips that best suits you before going to those levels with destiny modes. whatever you have is what's going to show up regardless of what units you have or upgraded and the equips you change after the first time. i played it like multiple times with different equips and units that's upgraded and unlocked and it's proven to be true.
i hate the fact that now, you have to train three ducks instead of one. it's boring doing the same training again and again. tedious of the fact that you have to win a tournament in order to unlock the next training area. i like ducklife 3 evolution better because it's more fun and you can train only one.
