Merge Tower Defense Roguelite Builder

Drag identical towers together and watch a tier-5 merge detonate across 300 enemies. Claude Code builds a complete merge tower-defense roguelite in one HTML file: 6 tower families x 5 tiers, 12 enemy types, 3 bosses over 30 waves, 15 run upgrades, summon pricing, sell zone, x1-x3 speed, bouncy squash-and-stretch juice, hit-stop and shake, synth music. Pixel art and sound made in code. Mouse, keyboard and touch. Variables re-skin the theme.
