Embark on a thrilling adventure to uncover the Lost Galaxy in *Astro Bot Rescue Mission*! Hidden within the game's main worlds lie ten secret portals, each leading to this exclusive area. A swirling icon next to a level's selection screen indicates the presence of a hidden portal within that stage. These portals are cleverly concealed, sometimes appearing early on, sometimes at the very end, demanding keen observation from players.
