Hi!
1. We might add some wardrobe options, but it's pretty hard to do since, for example, changing his sweater would require to redraw all the scenes where he wears one.
2. We haven't forgotten about Mothra, but yes, you got it right, we plan to rework it, since it doesn't really work in the current story, and her whole route doesn't feel up to par with rest of the content.
3. What version were you on on Android? We're pretty sure we fixed that one bug, but only in version 0.30.1.4, so if you still caught this bug with looping dialogue on this exact version — let us know!
