Isekai SOS

An unknown force is growing across the universe, draining the energy of every world it touches. Earth has sent out a fleet to answer their calls for help. When a world sends a summons, we open a portal to it. If the world still has energy, the portal stays open. If it has run dry, we spend a Spacetime Key to keep the gate alive. Isekai SOS is a fast, minimalist roguelike deck-builder. Every run has two parts: prepare at the camp, then fight the boss who is draining the kingdom's power. HOW IT PLAYS - At the camp (steps 1 to 9): open chests and altars, then choose 1 of 3 cards or upgrades to add to your deck. - The final battle (step 10): face the boss with the deck you built. - Only three numbers to manage: Health, Armor and Attack. Armor absorbs damage first, but it resets every turn, so every card play is a real decision. BUILD YOUR STYLE Mix cards from different archetypes, from armor stacking and shield-based damage, to berserker attack ramping, to armor-piercing strikes. Every choice pulls your deck in a different direction. RESTORE THE POWER Each victory relights another town in the kingdom. Once every town is powered again, keep pushing in boss rush mode: bosses grow stronger with every win, and your goal becomes beating your own record for the longest streak. KEEP THE LIGHTS ON Bosses retake towns while you are away, so come back and defend your progress. FEATURES - Short runs that fit into a few minutes - Multiple card archetypes with real deck-building trade-offs - Boss rush mode with personal best tracking - Daily tasks and bonus rewards - No account needed.
