I like the visual style and I think the lighting really compliments it. The narration was nice and I admittedly laughed at a couple of the puns. The music is good as well.
I think the ad did a really good job of being annoying. But I will say, it was a little cumbersome having to use the mouse to close the ad when the rest of the game is controlled by keyboard.
I did notice the game felt a bit better to control with WASD, compared to the arrow keys which felt a bit unresponsive. I'm not sure if this is just my keyboard though (I have a 60% one).
I'm not sure if the weapon the green bean is carrying is a gun, but it could just as easily be a turret.
Great work overall and it could be interesting to see the story continue. It works well as a self-contained story though.
