Introduction
Harry's Planets is a cozy 3D space adventure from developer chanch, made for young children and the grown-ups beside them. A small astronaut climbs into a chunky rocket and sets off on a trip where every landing brings a quick learning task: adding two groups of stars with answers from zero to five, removing stars without going below zero, or supplying one missing letter in a pictured three-letter word. Only three big answer tiles appear at once, so the screen stays calm. There are 31 destinations, the eight planets, five dwarf planets and eighteen selected moons, and every one is open from the beginning, so players can wander in any order they like. Nothing here can be lost: no scores, timers, lives or game-over screens. A wrong tile simply comes back for another try, and after a few attempts a colour hint quietly appears. Controls work with touch or a mouse. Drag a tile into the empty slot, or tap a tile and then the slot. Tapping stars speaks the count, while buttons repeat the prompt, jump to the solar system map, shorten the rocket flight, or mute sound. A settings screen holds music and voice volume, reduced motion, activity choice and a confirmed progress reset. The art is original low-poly 3D with painted textures, and giant planets get fantastical cloud platforms. Sizes and distances are simplified for play. Portrait and landscape layouts are both supported, with large touch targets, prerecorded narration and gentle original music.
