Nice game! I like the unique take on the theme by using A and I a little bit more literally.
Visuals are very cute and well made. Although I would recommend having the black outline on the player sprite also be around the bottom, so it doesn't look like she's floating. (Really only a hard issue with very small resolution games, most of my games also have this visual issue.)
I liked the story presentation, was nice to have a full cutscene for it.
The mechanics were cool, really got a lot of use out of two simple objects. I was really hoping that you would be able to put the A on the I and push it around, but I can see how that may be difficult to implement depending on how the rest is made.
Rotating felt a bit weird, and I think its because it rotates left and I think most games use rotate right.
The A beam felt a bit wonky, mostly when trying to leave it. Which can be troublesome for intended level solutions, especially when the solution you get may feel wrong.
Music is a jam!
Nice game!
