I built PokeSurvivor Online as an independent companion website for players who want clearer answers before and during a run. The site brings together a beginner guide, a move and evolution reference, and practical help for browser, phone, keyboard, sound, and save questions. Its homepage embeds the creator-hosted game, while the guide pages explain what to choose, when to switch active moves, and how evolution recipes work. I designed the site with Astro and Tailwind, focusing on readable navigation and responsive layouts. I’m looking for feedback on the information structure and mobile readability.
