This is a tricky one!
I love the concept you came up with and solving a level feels super satisfying. Unfortunately I did eventually got to level 23 and level 24 refused to unlock for me, despite solving it twice :(.
I really like the gameplay, the rockets motion can get really chaotic under the influence of multiple moons! However, this means that even a small change in the moon's position can cause the rocket to follow a completely different trajectory. For me (running windows/chrome) right clicking immediately always deleted the moons instead of dragging them, also on many levels I wasn't credited with the deleted moons. So often I would have to go to the menu and then restart the level from scratch. I think that addressing these issues would make the game more satisfying (and less frustrating on the occasions when a small change makes a close miss completely miss the target instead of hitting it).
I liked the minimalist style of the graphics and I felt the levels were always super clean and easy to read, which is great for a game like this. I also enjoyed the music and sound effects and felt they added to the experience of the game.
Aside from the technical issues, I think this is a really fun game that suits the theme of the jam very well!
