Defend your Life Orbs against ever-evolving foes in SimpleTD—with no microtransactions! Features -- Voiced Cinematic Cutscenes and Rich Story: A rich storyline to propel players through those waves with fully voiced cutscenes in a 2D, pixel art style with plenty of DLCs planned to expand on the story. -- 14+ Unique Towers, Each with a Personality: From all-purpose Simple Towers to credit-printing Mint towers, acid-splashing Splash Towers, boss-busting Shotguns, and range-boosting Buff Towers, every turret plays, and upgrades, differently. -- Interesting Towers and Mechanics - Easily collect crystals passively or organically by completing waves, store credits on easier maps to use on harder maps, protect your towers from aerial attacks. -- Deep, Permanent Upgrade Paths: Spend hard-earned Crystals in the Upgrade Lab to push damage, fire-rate, range, critical chance, and even global LP caps to dizzying heights, then stack buffs for exponential power. -- Endless Waves & Titan-Sized Bosses: Face adaptive swarms, enable Crazy Mode for 3x the enemies with 3x the strength, and face off against bosses with both set and random schedules! No two play-throughs will be exactly the same! -- Enemy Power-Ups: Instead of trying to earn power-ups for your towers, the enemies get a chance to! All maps have power-ups along the paths for enemies to pick up, providing unique abilities to power them through to your Life Points! --Daily & Weekly Quests – Knock out fresh objectives every day and week for Crystals, carry-over credits, and limited-time stat buffs that alter your next run’s strategy. -- 10+ Hand-Crafted Maps with Dynamic Modifiers. Spiral deserts, snaking forests, twin-lane battlefields, mega-sized arenas, and more.

No real-world money here; microtransactions are not welcomed in SimpleTD! -- User-Defined Graphics: Love retro pixel art? Leave it on. Prefer a clean, minimalist look?

VoxelReconstruct
Read full descriptionHide full description
VoxelReconstruct is a touch-first 3D molecular-assembly puzzle game. You pick atoms from the periodic table and bond them into molecules and crystals following real chemistry — every element has its own valence (the number of free radicals it can bond) and atomic radius, attraction and repulsion derive from size, and a curated bonding whitelist decides which atoms may join. Grow a molecule past a level's threshold and you win. It's a learn-as-you-play chemistry game, made for students building an intuition for stereochemical formulas. [How it plays] ‧ Touch-first: one "Mode" button switches between Navigate (drag to rotate, pinch to zoom) and Place (tap a free-bond dot to drop an atom) ‧ You place the first atom: an empty molecule grows from the moment you tap — nothing is seeded ‧ You choose the element AND the bond order: single –, double =, triple ≡, and coordinate → (a lone pair bonding into an empty orbital) ‧ Real chemistry: VSEPR geometry, ionic vs covalent bonds, multi-bonds that merge radicals so N≡N and O=C=O form naturally ‧ Advanced bonding: coordinate bonds build NH₄⁺, H₃O⁺ and metal complexes, with formal charge / oxidation state shown (e.g. [Cu(NH₃)₄]²⁺ = +2) ‧ Ring closure: two open atoms that come close can bond directly to close a ring (cyclohexane, etc.) ‧ The full periodic table (118 elements), each with its valence, radius and Jmol CPK colour ‧ Curated levels: each level fixes which pairs may bond and mixes in "trap" elements that won't stick — a wrong element is a mistake, three mistakes fail the level; some levels also require a variety of different elements ‧ Full-Table Sandbox: a free-play mode with every element, no mistakes and no failing ‧ Instant English / Traditional-Chinese switch, haptic feedback, progress saved on device (SwiftData) [Pricing] ‧ Free: the complete story campaign, fully playable ‧ Pro (one-time purchase): unlocks only the Full-Table Sandbox — build freely with the whole table ‧ Players who bought the earlier paid version are upgraded to Pro for free automatically [Who it's for] ‧ Chemistry students and enthusiasts building intuition for valence, bonding and 3D formulas ‧ Players who enjoy puzzle and building games ‧ Anyone who wants a gentle, hands-on take on atomic and molecular science [Privacy & Security] ‧ Game progress stays only on your device — nothing is uploaded to the developer ‧ No personal data collection, no ads, no tracking ‧ Built entirely with Apple frameworks, independently by Intoxicated Child Studio Reconstruct your molecules among the atoms
