Simple little game that's very polished considering the time you had, from the animation on the character to the feedback you get whenever firing a missile! The audio feedback was all really great too. I do really like how the missile was a traversal option as well as an attack, and the levels were designed well, though the difficulty level could probably be ramped up a little faster, the latter levels were challenging but there were a lot of intermediate levels that I felt like were way too easy.
However, I'm not sure if it fits the theme of the jam all that well as for all intents and purposes I have a lot more than one shot since I can refill it so easily, there are even a few levels that are based around you needing to return back to a single "refill" station repeatedly as you just fire your missile away at things, so it doens't really feel like I'm limited to a single shot.
