Interesting rocket jump mechanic in 2D games. I think that with more features and level interactions, this could become a nice and fun speedrun game. The graphics are simple, and while I can't say that Ilike them, I was surprised that buildings could be destroyed, making it a fun thing to play. I think these mechanics should be included.
The music doesn't match the graphics, as they're both 8-bit, but that's my opinion. And I'm unsure about the theme. It's kinda it, but not really. It's neither fish nor meat, as we say in my country. So, your game could be addictive, if you understand the mechanics. Or it could be casual, just for fun. You did a good job, so never give up and let's do more games)!
