« Boring » — My daughter « Yes, it’s pretty. Can you walk the dog? » — My wife « Hmm… I’m not sure I’ll understand it » — My mother So I walked Floc. And in the park, I found people willing to try my prototype. They played, replayed… and convinced me to keep building this game. Here is Molekula: a minimalist, relaxing, hypnotic puzzle. A game that doesn’t rush you, doesn’t stress you, doesn’t demand anything. Just you, a few molecules, and a quiet moment to breathe.

About

Blockstellar

Read full description

Two hundred handcrafted levels. A bomb that counts your moves instead of your seconds. And a daily board where you can watch someone take your crown, then go and take it back. Blockstellar fits gem pieces onto an 8x8 grid in deep space - but the parts you will remember are the ones this genre does not have. JOURNEY - 200 HANDCRAFTED LEVELS Ten cosmic chapters, from Nebula Fields to Golden Infinity. Every level traps gems inside the grid and gives you a fixed budget of pieces to free them. Finish with room to spare and you earn all three stars. A designed campaign, not an endless mode with a level counter bolted on. THE FUSE CORE AND THE NOVA SURGE A Fuse Core lights up on the board like dynamite - but it does not run on a clock. It counts down on your piece placements, so it never punishes you for thinking. Clear the line it sits on for a bonus, or let it burn out and lose a Nova Star. When the board finally locks up, a Nova Star powers the Nova Surge: the centre detonates and the run keeps going. THE NOVA BOMB A 3x3 piece that clears everything around it, dealt into Endless runs. Not a purchase, not a power-up to grind for - it simply arrives in your tray as part of the game. RACE THE GALAXY, WITHOUT AN ACCOUNT Every Endless run can post to a daily and a weekly board. No sign-up and no typing: the game deals you a callsign like NovaPilot, and you reroll until one fits. The board tells you who overtook you while you were away, who is still in reach, and exactly what it costs to take the top spot back. Would rather keep to yourself? Skip it, and it never comes up again. HOW IT PLAYS Three pieces at a time. Drop them anywhere they fit, in any order. Nothing falls and no clock runs, so the board only fills as fast as you fill it - every game over is a puzzle you built yourself, and every clear is one you earned. 33 piece shapes, and the dealer guarantees at least one of your three still fits whenever that is possible. COLLECT AND PROGRESS - 5 jewel-bright block skins to unlock with coins you earn - 20 player ranks, from Stardust Novice upward - 18 achievements to hunt down - 3 fresh daily missions, every day - 7-day streak rewards that keep climbing - Your five best runs, kept on your device MADE BY ONE PERSON Original artwork, an original soundtrack, and a live announcer who genuinely cares how your combo is going. Every clear pops, and every big combo shakes the screen. OFFLINE, NO TIMER, NO TRICKS Plays offline: every mode and every level, with no connection needed. The optional leaderboard is the only online feature. No timer, ever. The only pressure in the game is the Fuse Core, and it counts placements rather than seconds - put the phone down mid-run and nothing moves. Free to play, with advertising kept polite: rewarded ads are always your choice, plus an occasional interstitial between runs. One purchase - Blockstellar Deluxe, one time - removes every ad, unlocks all four premium skins instantly, and gives you two Nova Stars per run instead of one. No subscriptions, no coin packs, no loot boxes, no energy system. Every reward is fixed and known before you take it. Every mode and every level is in the free game. Nothing is walled off. WHO IT IS FOR Players who want a puzzle campaign with an ending, not just a score counter Brain training and logic fans who want a workout without a stopwatch Commuters and travellers who need something that works with no signal Anyone who wants to think in peace, with no clock ticking How far can your nova reach?
