The game is too slow. It needs more content and options.
What the heck is with this trend of people labeling games as RPGs when they're clearly not. If you're going to mislabel a game, then it had better be exceptionally good to win people over after the initial disappointment of discovering it's not what they thought it was. And this is far from exceptionally good. Slightly better controls than the other comet defense game, but just barely.
Bottom line, file your games under "shooter" where they belong and stop relying on the popularity of RPGs to draw people to your mediocre games.
i think it moved to slow to really play it..
