im going to say good game so far mission 9 i think im on 15 battles in. but im experiencing bugs with units on the hill not being able to hit each other making me wait for either me to summon a range unit if i have room or them... also what i dont understand if they are above me they can hit me but me not them in melee yet when its the other way round they dont move and my guy swings at nothing..... apart from this its addictive.
also i think it was bugged as i went back to the upgrades and still managed to see things that werent upgraded... things like the bg thinks on info pane 1 and some others.
cant tell much difference between most of the bubbles in a sense that i dont know what as BFT tank is or a destroyer even though apparently i completed the game without seeing one of them... however needs a save button or continue later. and was actually quite fun to play although i found deranking of my bubble as i got bigger far too annoying as the size of my unit didnt help ¬¬
thunderjutsu mentioned who has the most mana at lvl 30. so i guess the green is the best hero. however i recommend using him later as you need to use the others to unlock all the cards. so if you leave him last, you can then do what im doing and use him to do the caves.
