Hmm, a pretty decent implementation of Buster Bros gameplay! For the most part, I feel like the game is taking good strides in recreating that classic arcade fun with lots of fun power-ups and satisfying bubble popping. I love the little things you've put in like how the score counter spins up and your guy gives a little victory pose at the end of each level, along with other things like the world map and so on: very cute stuff! I also found the artstyle of the game somewhat charming: it had this weird old-school Geocities aesthetic to it.
However, I gotta admit that the game got quite boring for me rather quickly: I was already ready to quit around halfway through world 1, but I pushed on, hoping it would eventually introduce some sort of new obstacle or fun mechanic to keep things fresh. However, once I finally got to world 2, all I was rewarded with was a new bubble enemy that, while it looked different, it was exactly the same as before. It just felt way too repetitive overall and I could never see myself getting through all of the worlds: it just lacks any sort of variety or sense of progression to keep things interesting for me.
