I really enjoyed this game ! I love those games with minimum control.
Few things :
- there is a peak of difficulty just before reaching the grandad, with a lot of flying enemies (or was my strategy wrong ? I should have boosted Mom's health maybe)
- Small bosses before each family member release would be cool
- The congratulation screen is way too poor in comparison to the intro and the game. Two of three comic strip picture with punchlines of all members of the family would be nice.
