Lmao, thank you very much xD
Yeah the boss softlock is something I really shouldn't have overlooked, I won't be letting something like this slide again on the future, that's for sure.
And the game was pretty rushed indeed, I planned on doing way more stuff (even overscoped a bit for the fun of it), but hey, I'm glad everyone is already having fun with what I got out done :)
Also, for the mouse space issue, you can hold Z to invert your aiming, so that makes Yu shoot herself to the direction of the mouse instead of the opposite of it, this should help you manauver more efficiently.
