The characters are unbalanced.
The 2 characters on the second row are way too powerful. "last flake" is invincible with a level-5 regen and a 160 HP. The skills of the 3 characters in the first row, especially "the detective" and "the student", need to have shorter cooldowns and be more powerful.
Why can't I cast a spell in battle? I have the "Mage Staff of Accuracy" whose ability is "FIREBALL"?! however, whenever I click "cast a spell", every spell was gray.
what is the name of the last mission of the Tyrian quest line????? I guess I have to do it again to get the badge.
I've finished the game, including all quest lines, weeks ago and the badge won't recognize that.
For the last lvl,
1)build basic laser don't upgrade;recycle;rinse and repeat.
2)use TFL laser, only for mother ships.
I lost 6 basic laser, 3 TFL in total. And have 600M at the end of the battle to spare.
good luck
