I liked the idea behind the game, although, like others said, it seems a little lacking - I'm sure next time you'll be able to do a lot more! I think some things you could try doing for next time is to make more detailed artwork, maybe a spacey background that fits with the whole meteor thing, possibly some items - maybe powerups, maybe some different meteor types (i.e., comets or asteroids), maybe you could have some of these come with aliens that try to attack you on their way down. I'm sure there's many things you could think about, if you want you could make a list. Otherwise, nice job for your first itch game.
I've been trying to rate a lot of games, so if you could rate and give some feedback that would be greatly appreciated!
