That was intense! Got to a score of 500 before getting tired, but something about blowing up the red moons (great particle sound effects) was super satisfying. I though the most interesting part of the game was when I had 3 launchers, for the simple reason that the two-launcher and four-launcher configurations were symmetric. Having three launchers arranged asymmetrically means that the optimal strategy is just to aim for the closest moon but possibly to make sure you're lining up a shot with 3 hits as well (which is something you could have explored by making all launcher configurations asymmetrical). I feel like this could very easily add some depth to the game.
The presentation of your game was super clean and I especially liked how smooth the aiming control was, that felt great! I really got a sense of becoming more powerful with each additional launcher, and I think you could have easily gone above the maximum four launchers and increased the difficulty a bit more (but maybe that is still to come). Nice work!
