can't beat lv 30, enemy units spawn too fast with a range that cover all the screen, it's impossible! My units die on the spawn point without firing at all ._.
i noticed something interesting, if you attack the enemy unit from behind there's a higher chance of better damage (tested in war academy) most of the time 15~20 damage on normal attacks, my general did 228 damage on a critical (instant killing the enemy unit xd), not only i noticed the higher damage, but they also don't counter.
that really helped to avoid 1 damage attacks
the stats up message when you lvl up is completely bugged, the horseman still receive + 3hp + 1 leadership even when it says -12 -3 and the wizard still receive +4 +4 even when it says +10 +10, just visual bug.
