Thank you very much for the feedback and video! I see now from this and a bunch of other comments that the beginning of the game is very unclear. Just to clarify, you did not miss anything and were not supposed to have the hookshot yet, and the large missiles were a part of defeating the first boss, as you had to guide them to the top of the arena. You even did damage to it once on your first playthrough but I see that we did not add enough feedback for that to be apparent.
I can also see that the base player movement is lacking, I thought that it wouldn't be that big of an issue once the players unlock the hookshot but because of that, I guess a good chunk of them never got that far to begin with. But that is how it goes with these things sometimes haha.
If you would like to take a second look at it at some point, I would recommend downloading the fixed version, as it is the same as the original submission version but it fixes a couple of major issues related to performance. I kept the original version up as I felt it was against the game jam spirit to remove it completely.
Regardless, thank you for taking the time to play and record your playthrough of this game, and a bunch of other games here! It has been helpful and I am sure it has been helpful for other developers as well!
