I’m Marko Krulc, and Krulz Games is just me, working from Slovenia. Every line of code, every pixel and every physics tweak passes through my own hands. Most phone games bank on mindless distraction; I build games that demand your full attention and invent new ways to play. No ads, no pay-to-win, no corporate filler.
NodBlocks: Face Block Puzzle is the only block puzzle you control with your face. Turn your head to move a piece, raise your brows to rotate it, open your mouth to drop it, look up to pause. Four gestures, zero taps: an 11×22 board and thirteen piece shapes, played start to finish without touching the screen — menus, gameplay, and even typing your initials onto the global leaderboard.
It is free on iOS, needs iOS 16 and a TrueDepth camera, and reads facial blend shapes through ARKit entirely on the device: no video or image of your face is ever recorded, stored or sent anywhere. That makes it playable for people who cannot use a touchscreen at all — the accessibility page covers what it needs and where it stops working. Play it in your browser first; the demo needs no camera and no download.
Rev Rush: Pixel Moto Runner is a one-tap reflex runner through 21 handcrafted pixel worlds — desert, thunderstorm, volcano, outer space, neon city, glacier, magic forest. The speed keeps climbing, every jump counts, and a single crash sends you back to the start line. Coyote time and jump buffering keep every death fair.
Two rides, a garage of 51 colours, a global podium, twenty languages, and it plays offline. Free, with never an ad. The one optional unlock hands you things sooner and never more: a paying rider still carries exactly one shield and one life, the same as everyone else, so the leaderboard keeps comparing rides and not receipts. Take a ride.
The ship above is already flying and there is no start button. Nothing here is an image file: the logo, the ship, the enemies, the explosions and the nebula behind them are all generated in code from a fixed sixteen-colour palette, and every sound is synthesised in your browser. The lettering is drawn from character maps, so there is no web font to download either.
There is no framework and no build step. The whole site runs under a default-src ‘self’ content security policy, which costs nothing to enforce when a page loads no third-party anything. The same code that draws this page also renders the share images at 1200×630 — they are a screenshot of the site, not a separate drawing.
There is no studio boardroom and no support bot. Bug reports, publisher enquiries and streamer requests all land in the same inbox and get answered by the person who wrote the code, usually within a day or two. Press material — screenshots, logos at the size you need, uncompressed capture — is sent on request, normally the same day; the press kit has the fact sheet and the footage.
