Found a bug. As I was fighting the Apple Tree for the 3rd ingredient, I clicked for one of my characters to attack just as the tree killed the character, and the game froze up. It'll still react if I try to go to the options menu or whatever, but I can't go on in the game.
A good game. 4/5. The only problem I had was that there was no real sense of difficulty other than slightly finicky controls. More enemies shooting, or less time allowed for pickup, or making the ships actually sink when the mission briefing says they are would be a good improvment.
But I very much enjoyed it, especially for a first flash game. :)
