Grimward — Tower Defense

Tower defense, the way it should be: no ads. No tracking. No always-online. Grimward is a sci-fi tower defense I (Andre, a solo developer from Switzerland) built over months in my spare time. A hobby project, not a free-to-play skinner box. You pay once, you get the whole game. 🛡️ PRIVACY-FIRST — THE HONEST DEAL - No ads. Ever. No pop-ups, no "watch a video for 30 gold" mechanics. - No tracking. No analytics, no Firebase, no ad SDKs, no telemetry. - No internet access. The app doesn't even request the INTERNET permission — check it yourself in the system permission manager. - A single permission: VIBRATE for haptic feedback. Can be disabled in Settings. - No user accounts. No cloud saves from my side. Your progress lives locally on your device. ⚔️ DEPTH OVER FILLER 6 towers × 3 upgrade levels × 2 end-spec paths = 36 unique tower builds. Plasma-Inferno, Tesla Ion-Lance, Railgun Crit-Sniper, Cluster-Mortar, Disruptor-EMP, Reactor-Strike — each spec choice changes your loadout decision tree. No single build dominates; every map asks for a different setup. 👹 MULTI-STAGE BOSS WITH PHASE-2 TRIGGER At 50 % HP, every boss flips into Phase 2: pulsing aura, new add-spawners, a new threat layer. The Wave-20 final boss is an 80-second climax fight with a red energy shield phase (CC-immune until the shield breaks) and adds spawning right at the path start. Not a DPS check — actual phase management. 🗺️ CONTENT - 5 campaign maps × 20 waves — City Ruins, Desert Highway, Arctic Station, Swamp March, Industrial Yard - 3 endless modes — procedurally generated, fully deterministic (no RNG luck, same setup = same wave) - 24 cosmetic achievements with progress tracking, 3 of them hidden - 4 music themes — Default, Industrial, Synthwave, Bio-Hazard — unlock via achievements - Tower-Mastery system — lifetime kills per tower kind unlock +2 / +5 / +8 % permanent damage bonus - Tower construction phase — placed towers take 3 seconds to build (cancel anytime, 100 % refund) 🎧 AUDIO + VISUAL POLISH OGG-Vorbis music with dynamic boss crossfade (main music fades to 0 %, boss-pulse layer fades in). Combat-juice pack: screen shake on crits and boss hits, coin float on kill, defeat slow-mo, boss-death spectacle with shockwave rings. Every gameplay second feels reactive. 🌍 FULLY BILINGUAL German and English, switchable from the main menu. Both languages hand-maintained 1:1 — no "AI-translated filler German". 💰 FAIR PRICING One-time purchase. No IAPs. No pay-to-win towers. No "lives / energy" mechanic. You buy, you play, done. 📱 SYSTEM Android 7.0+ (API 24). ~50 MB download. Smooth (60 fps) on older mid-range devices — tested on Samsung Galaxy A-series. ——— If the free-to-play wild-west is getting on your nerves and you just want a game that works like a game — give Grimward a shot. Bug reports and feature requests welcome — the app has a built-in crash-share button (Settings → Advanced) that drops the log into Android's standard share sheet. Send it my way via mail or messenger, I read everything. — Andre, solo indie from Switzerland
