You can't save, the game is way too easy, there are no enough upgrades and things to buy, the game gets boring pretty quickly and you can't really upgrade "archers" and "mages" if you have only 1 archer and 1 mage... doesn't worth wasting time.
At the last sector I have reached the left wall and there is no spaceship on the way there... Your captains must really want you to die if they trick you like that. 5/5 great game
great game... 5/5... it's like Orpheus and Eurydice... he tries to bring back a soul, he shouldn't look back, and he fights a giant dog like Cerberus. xD
