What happens when fire meets water? Something new. Alchemy Lab is a cozy discovery game where you combine elements to uncover what’s hidden beneath the surface. Start with four: Fire, Water, Earth, and Air - and experiment your way into a world that expands with every discovery. No timers. No pressure. No wrong answers. Just a warm workbench… and your curiosity. HOW IT WORKS Pick two elements. Place them on the workbench. Tap Combine. If something new emerges, you’ve made a discovery. If not, the workbench gently encourages you to keep exploring. Every discovery expands your collection and opens new paths forward. Some combinations feel obvious. Others reveal themselves slowly. The best ones feel like you found them, not followed them. WHAT YOU’LL FIND • 60+ elements to uncover across evolving tiers • 100+ recipes with multiple paths to discovery • A hidden workshop that unlocks as you go deeper • Timed transmutation for rare, higher-tier elements • A Tinkerer’s Journal to track your progress • Flavor text that gives each element its own voice • Gentle haptics and animations that make every interaction feel satisfying • Ambient sound that deepens as your journey unfolds DESIGNED TO FEEL GOOD Alchemy Lab isn’t a race. It’s a place. A quiet, creative space where ideas come together and small moments of discovery feel meaningful. There’s no punishment for trying something new. No pressure to optimize your path. Just a system that rewards curiosity… and waits patiently for your next idea. BUILT FOR DISCOVERY Some players think logically. Some experiment freely. Alchemy Lab supports both. Multiple recipes can lead to the same result, so there’s no single “correct” path. Your journey unfolds in your own way, shaped by the choices you make along the way. MORE TO COME There is more to this place. New elements, recipes, and systems are already in development. Complete the current collection to catch a glimpse of what’s being crafted next. Built with care by a solo developer at Forgebound Labs.

Slip into the terminal and break into a chain of secure systems, one puzzle at a time. Decodia is a hacking-themed logic puzzle game. The hacking is all story; the gameplay is pure puzzle solving, so you never need to know anything about computers or code. Every mission is a short break-in with several gates to crack: • Code locks: read the colors of earlier wrong tries and deduce the code. • Token forging: overlay circuit fragments until they match the target exactly. • Network rerouting: rotate pipe tiles until the signal reaches every node. • Word locks: guess the hidden word; the colors show how close you are. • Word hunts: find the words of an intercepted message hidden in a letter grid. • Infiltration: step past turning cameras and reach the exit unseen. • Code probes: read the scored guesses and name the hidden symbol code. • Firewalls: slide blocks out of the way to free a trapped packet. • Signal maps: rebuild hidden pictures from row and column clues. • Uplinks: wire numbered servers together with straight cables that never cross. • Laser locks: flip mirrors until the beam lights every receiver. • Frequency jamming: give linked transmitters different channels. • Data push: shove data blocks into the shredder slots, one step at a time. • Circuit tracing: solder one unbroken trace through every pad on the board. • Data sorting: move packets between stacks until every symbol has a stack of its own. • Checksums: fill digit grids until every row and column adds up to its total. • Alibis: match suspects to their login times from a handful of clues. Side jobs branch off the map with puzzles of their own: binary grids, logic-gate locks, packets sliding on ice and trap scans. Every wrong answer raises your trace; fill the meter and the system rotates its keys. Stuck? Up to three hints per puzzle; the first is always free. Finish missions to unlock the next ones, earn BREACHED, CLEAN and GHOST ranks, and collect 30 achievement badges. Can you clear a mission with no hints, no trace and under the target time? • 60 handcrafted missions in 12 chapters, plus 4 side jobs • 21 kinds of puzzles, all solved by logic, never by guessing • Free to play: energy for new missions refills over time, and Chapter 1 and replays are always free • No account; one optional purchase removes all ads and gives unlimited energy • Plays offline; your progress stays on your device • One-handed portrait play with sound and haptic feedback • Play in English, German, French, Italian, Spanish or Turkish
