Thank you for the comment!
Though it may seem that Nari's attacking frame is missing a neck, it is the just parts of her hair that blocks the view of her neck after I looked over at the other frames where that part of the hair appears to be in front of her shoulders. At least that is what I assume.
For the Space thing, yeah I'll definitely need to change that. Might as well do it when the match is over, in which I'll make a retry button for the mouse as well.
The Recommendations sound awesome and simple! I'll try my hand at implementing those parts of the game!
