I love the artwork and the use of the resolution constraint. The music is catchy, and the sound effects are perfect.
I did find myself settling into a relatively uninteresting gameplay loop. I never swapped out the pokemon and just kept hitting attack, then capturing once the health is all the way down to 1.
It's too easy to progress through the game by mashing buttons, and there needs to be something to prevent that strategy so we can explore other more interesting strategies.
