This is pretty cute! While I do like the simplistic style you were going for, i would like to see this be at least a little bit more fleshed out. I think some more work in the character design would be nice. Backgrounds are a really big thing for me, and you don't really have any of that going on here. Anything is better than nothing, just some splashes of colour, or if you wanted to keep it black and white maybe just some little details to give it more of a setting. You definitely could have spent some more time on certain drawings; for example, the table doesn't look all that great. Also, for the animation style, I do like the sort of wobbly effect you achieve by having two different drawings of the characters alternating between each other, but I think it should be a little bit less extreme to make it easier to look at, and maybe include a few more different drawings and frames so it doesn't look quite so jumpy but does still create that effect. Finally, I think you could put a bit more work into sound effects, even if it's just simply using more sounds.
Like I said, I can definitely appreciate the style you were going for, so I put my vote this high out of principal, but I really do think it could be carried out a bit better. If you have any questions, feel free to message me. I'm looking forward to seeing more from you!
