Starfall Spire is a sci-fi roguelike deckbuilder for Android. Command a battle mech with cards: 4 mechs, each an independent combat system with its own talents, exclusive cards and energy mechanic; 200+ cards that create cross-mech synergies; 86 alien enemies that coordinate their abilities and punish sloppy play. Its twist: dying raises your Luck — the more runs end, the more your shops and rewards roll rare cards, so every failed run funds the next. Free on Google Play (optional IAP).
