7 Days of Summer with My Childhood Friend

A pixel-art H-simulation game set during a 7-day summer vacation. You play as a male protagonist spending time with Mizuno Ui, a childhood friend with a passion for insect collecting. The core loop involves catching insects as gifts to raise her affection, selling your catches at a shop to earn money for items that aid collection, and unlocking increasingly varied sexual scenes as you progress. The game features numerous animated erotic scenes including handjobs, blowjobs, and various sexual positions, which unlock based on affection level and specific insects caught. Ui's character design emphasizes her athletic tan lines and innocent unawareness of her own appeal.
