Sphere TD vs HexTowerDefense

Sphere TD is a tower defense game with one difference: there are no preset towers. You build every tower yourself, then send it out to defend your base. WHAT IS IN THE GAME - 39 towers, each with its own grid layout and function - 33 mods, each with tiers, MK upgrades, a B-Side function, and 3 perks - 50 hand-crafted maps with three objectives each - Endless mode after map 50, plus map-specific challenges - A research tree, mod crafting, and a trader - Spheres that scale into elites, bosses, armored, shielded, cloaked and flying - Offline play, with cloud sync and leaderboards - Cross platform: mobile and desktop NO NONSENSE No pay to win. No time gates. No paywalls. No ad spam. No loot boxes. Funding the Galatium Academy is appreciated, never required. MESSAGE FROM THE DEV Hi, I'm Alex, a solo developer, and Sphere TD is my first game. If you like tower defense, meta progression, and theorycrafting builds, you should feel right at home. Come discuss tower builds with other friendly cadets on Discord. I am committed to 10 years of support. You want it, I'll make it. Ready to join the Galatium Academy?
