This was a very fun and polished game! I can see that a lot of passion was put into this game to make sure the user has the best experience possible.
A minor nitpick I had with the game was the theming. In the story, you are risking your life to get the biscuits, but in the gameplay, there really isn't any risk elements (dying isn't really considered a form of risk unless there may be luck elements or choices for the user involved).
Fulfilling the theme in the story is a bit weaker than showing it through gameplay, however it still works! Following the theme too well really shouldn't be the main focus, as we're just trying to make a good game.
The art is nice! I like how the butter gets bigger with more ammo, nice detail. The intro cutscene was also very well detailed with a voiceover, awesome way to show the story.
The gameplay is quite good and simple, I like it. Shooting and dodging enemies is a pretty good recipe for an engaging game.
The final boss is quite challenging but still feasible, definitely quite a spike from the part before it. Very good boss 👍
Incredibly polished game! Good job.
