For an eroge adaptation, the art actually looks good in my eyes. Or at least, it's like 10x better than Akane Iro was visually. The backgrounds, especially the ones in the forest, looks pretty darn awesome IMO.
And osananajimi heroine? Ganbatte! Gonna be an uphill battle as Ui looks to be the 'main heroine', and she hasn't shown her current self yet, but like all the girls, she has a chance. Just hope no omnibus nor no harem ending in the end lols; I'd take a loss over either anyday.
