I am giving this a relatively high mark for a point and click puzzle game. It has a lot of problems though. One at least one occasion you could not pick up an item because it was behind the "gamesfree.ca" link. Not so good guys.
I have to say, this game misses the point of making an "Educational Game." Theres no real game here. You might as well use flash cards and a stop watch. Author - Please don't be discouraged by this comment. 95% of all so called "Educational games" completely miss the point of being a game as well as educational. Take a look at, say, Cellcraft, for a good educational experience in game form. (Admittedly, I'm a few too many decades from HS bio to know for sure how accurate it is...)
Game very good. I think having to upgrade the slots on an already expensive new ship to use the extra weapons is more tedious than it needs to be. But otherwise very cool. Could use a "You won" screen once the last boss is killed, but that is just nit-picking.
