Head Heist is an action co-op 3D third-person extraction heist where instead gold and money you steal something more precious, human thoughts. Inspired by the layered dream logic of Inception, the agent confrontations from The Matrix, and the mind-diving mechanics of Psychonauts, the game puts you inside NPC minds navigating procedurally generated levels while managing a physics-based tactical backpack. Each run can be approached through stealth, force, or a combination of both.

The game runs across two modes. During the heist itself you infiltrate, dodge suspicion and extract mind fragments. Each fragment carries a story, a memory, or a secret with a market value. In the shop simulator, unlocked after each run, you price and sell those fragments, turning what you stole into a second strategic layer. A post-heist Narrative Impact Report then shows how your intrusion permanently changed the target.

Developed with the Prague Game Accelerator, which provided funding and mentorship. Showcased at GDS Prague where it drew attention from key industry figures.

Scope and identity defined the development. The team was small and shifted during production, creating constant pressure to reshape features. Every step toward a better concept also shifted the game's mechanical identity, making it hard to lock a stable foundation. Making the game not just technically interesting but genuinely fun was its own challenge: tuning tension, pacing, and reward loops alongside a novel premise required constant iteration. Pitching to industry veterans added another layer: the game drew from co-op extraction trends that not all experts were immediately familiar with, making the vision hard to picture without playing it.

To stabilize the development, I established clear Design Fundamentals. This framework quantified every aspect of the game. From procedurally generated mind levels and unique VFX to complex NPC behavioral models. By setting MVP, Viable, and Ideal values for features like the physics-based backpack, 'Butterfly Effect' narrative reports, and dynamic environmental transformations, the team gained a concrete roadmap that balanced technical complexity with core fun.

The redesign builds on user testing of the first version: people didn't understand how the game worked until they actually started playing. Guzzle 2 therefore puts the game first. The app opens straight onto the cards and everything else steps into the background.

• Straight into the game: the menu-driven home screen is gone and cards are swiped away Tinder-style. Adding players, card packs, community, favourites and the quiz live in a side menu.
• Packs as toggles: instead of checkboxes, each pack is individually “mixed into the game”. New packs were added (Vote, Dare, Icebreaker) plus an optional Spicy pack.
• New visual identity: a dark background, every category has its own neon colour and a large outline icon, and headings use the Playfair Display serif. You can tell the card type at a glance, even from across the table.
• Smarter gameplay: Virus and Disease cards “cure” themselves a few rounds later with a follow-up card for the same player, the language can be switched mid-game including the current card, and TVs and non-touch devices get button controls.

An interactive multimedia project guiding users through the full legislative process in the Czech Republic, from a bill's first draft through parliamentary readings, committee review, and presidential assent.

Narrative & Script: Wrote the story structure and script that gives the experience a human arc instead of a dry procedural walkthrough.

UX/UI Design & Visual Identity: Led the full interface design, covering information architecture, interaction flows, screen layouts, and the visual language throughout.

Video Production: Directed, edited, and produced the final case study video from shot structure to final cut.

Translating a topic that is inherently procedural and jargon-heavy into something emotionally readable for a general audience. Making it engaging without sacrificing accuracy was the constant balance. The 3D environment and layered interaction design turned an abstract civic process into a space users could actually move through.

The task was to create a short explaining video for one of the Laws of UX: the Doherty Threshold. Based on the positive feedback on my previous video titled How a Law is Made, I decided to use 2D motion design again and create this project in this engaging way.

An open-source text-to-speech reading app built to make studying and reading more accessible, with full Czech support. The idea was born during my studies in Japan, where every subject required reading through mountain of case studies. I found that listening to the material made it significantly easier to maintain focus and process information than struggling through long, dense texts. Built solo using open-source voice models including Piper and Kokoro.

Upload any PDF and have it read aloud with a single voice. Navigate freely through the document while it reads and use the table of contents to jump between sections. The reader tracks your position and highlights text as it goes.

Rendering PDFs natively inside the app and precisely synchronising a moving text highlight over the rendered document as audio streams, making the cursor feel natural rather than mechanical.
