LoopTide TD

LoopTide TD is a minimalist single-player tower defense roguelite. Enemies march along a single non-closing spiral track toward a central leak point. Each run you:

• Draw towers: start with 3 of 8 tower types (arrow/cannon/ice/electric/poison/aura…) drawn into your pool by rarity;
• Merge to evolve: pair two towers, two Lv3s, or two awakened towers to forge advanced towers; ice+poison→Wither, arrow+electric→Thor, three auras→Altar (field-wide damage/attack-speed/range buff);
• Build up: stack relics (up to 6), talents, and tower awakenings for a unique run each time;
• Three maps: meadow / lava / ice differ in enemy speed and layout, with auto 90° portrait adaptation;
• Zero asset dependencies: fully procedural textures + WebAudio synth SFX — loads instantly, no external requests.

Landscape & portrait supported; Simplified Chinese / English bilingual.

绿色循环塔防是一款极简美术风格的单机塔防 Roguelite。敌人沿一条单螺旋不闭合跑道循环逼近中心泄漏点，你需要：

• 抽卡获塔：每局开局从箭/炮/冰/电/毒 + 光环中抽 3 张进池，稀有/史诗概率分层；
• 合成进阶：同塔 ×2、双 Lv3、双觉醒可合成进阶塔；冰+毒→凋零、箭+电→雷神、三光环→圣坛（全场增伤/攻速/射程）；
• 构筑成长：遗物（最多 6）、天赋、塔觉醒层层叠加，每局构筑不同；
• 三图差异：草甸 / 熔岩 / 冰原，敌速与地形各异，竖屏自动 90° 适配；
• 零资源依赖：全部为程序化纹理 + WebAudio 合成音效，加载即用，无外部请求。

支持横屏/竖屏，简体中文 / English 双语。
