Absolutely love all the effects you put into the meteors, everything from the smoke to the explosions feels great! The character is also cute, what a good lil lad.
I think the audio could use some work just because it feels off for whatever reason, but I'm not sure I can really pinpoint why on this point. If I were to guess, it would be the shooting sfx but I can't be sure. The rain in the background also feels choppy and distracting, but it's definitely a good start to a pretty cool effect!
The actual mechanics are simple but they definitely work, the only thing I can say is that refining some values a bit might make it more fun but all that's something to play around with hehe.
