I love the atmosphere and depth of the game, very well done. I was happy to play through the whole thing, though I didn’t make it further than shattering the “crystal” at each planet. Was there anything more to do?
A handful of things I ran into: finishing one planet didn’t correctly flag it as unlocked. Also, gather the log/disk things didn’t seem to register in the “inventory” or progress screen. Finally, in the secret area at the base, I tried to use a special attack with no special selected, and it froze the game.
