It's going pretty well. The gameplay, background, weapons, enemies, music - everything is monotonous, but nothing becomes overly boring. Only pleasantly familiar.
I like that the enemies are of different speeds. I don't like that it's not clear how far to the next level. Enemies in moderation. Hearts too. Perfect balance. Jack is good. Its image, design and music reek of old movies with tough macho men, a little less gallant than Indiana Jones. Bee animation is a separate kind of beauty here.
