The Google vertical metrics specification states that the winDescent value must be -288, and that no glyph can be deeper than that value in order to avoid risk of clipping. In Tsukimi Rounded, there are several glyphs that exceed that value:
J
g
y
yacute
ydieresis
exclamdown
questiondown
micro
The lowest, exclamdown, is at -311. As such, I suggest scaling the font by 12% (or at 88% in the Glyphs transformations pane) to ensure that all glyphs remain within the BBox.
