About

Defend Your Flame

Features
Read full description

Grab the nearest skeleton and throw it into the sky, or into another enemy! Defend Your Flame is tower defense you play with your hands. Enemies march on your wall; you grab them and throw them. Fling one high and the fall finishes it. Pitch them into each other. Slam bats into the dirt. Can't grab a mage? Throw an enemy at it. During the wave you spend your Flame: raise auto-firing totems, load a catapult that hurls back whatever you drop on it, hire a blacksmith who repairs mid-fight, grow two spell lines. Most upgrades lock out the others, so no two runs match. Then the bosses show up. - Survive bosses at rounds 10, 20, and well beyond - Final Stand: buy everything up front, then last as long as you can - Global leaderboards and personal bests - Hand-drawn pixel art, original soundtrack, plays offline
