spoiler alert
i did beat 6, just took all 8 of them to get a red , which u get after it, last one u got to use the right troops for easy win, if u send the wrong troop they get wiped out, weapons and armor upgrades can make the game more challenging if u don't buy any, also hiring some troops
do a new game see if u can just beat the game with first 8 troops with no upgrades for campaign
i agree a pause so u can move your troops to different spots at battle beginning would be better, not sure but during a replay you don't get xp maybe bug, last thing might be good if you could buy something for armys u can't control to make them better, at stage 6 they die faster than my troops can help them, maybe some achievements in game might be cool, also at kong
suggestions for next one or upgrade, i do think 2 mechs on 2 mechs would be better.
2nd one is multi player like in a tournament or maybe a daily or weekly matches where u pick a strategy to use example kill legs first, then arms, last body, using best weapon for each part.
with some limits like only grade like E, D, C, B, A for all parts , each tournament can have the rider posted so its fair game for everyone
some achievements on kongregate might get players attention more
this game does have a good potency to grow
u got like over 166k plays in about 9 days, enough for almost a player base for muli player route to change into
