I really like the idea, though at least for me it needs some tweaks because it felt too hard not always in a challenging way but in a chaotic way. I think it's a bit too fast, and having to change the trajectory while the rocket is moving but not being able to predict exactly how it will turn out can cause a lot of errors that feel frustrating.
But overall I enjoyed it, it's a fun mechanic and the art is charming, nice job.
