Heart Horror

Heart Horror is a browser-based bullet hell shoot-em-up game.

The core of gameplay is to avoid bullets, partially by recognizing and remembering enemy boss attack patterns.

The avatar you control is a lot larger than your hitbox – enemy bullets may touch your ship and yet you will not take damage. Only if the bullet touches the very centre of your ship will you lose a life point.

Oracion Online

Oracion Online is an online collectible card game for one or two players. It is in Czech only. It was created as a school project in the summer of 2016.

I invented the game Oracion, in its paper form, in 2009 for my Scout group and in the years 2009-2011 I used it in my patrol as a motivation element.

Oracion is a simple card game. Each round, each player plays a creature card, attaches tool cards or uses special actions, and then rolls dice. The number and kind of dice is determined by cards. The player who rolls the higher total “defeats” the opponent’s creature. The first player to defeat four of their opponent’s creatures wins the game.

The Deadlock Empire

The Deadlock Empire is a programming puzzle game created in a team with Michal Pokorný for the 2016 Hack Cambridge hackathon.

In the game, the player assumes the role of a computer scheduler. In each level of the campaign, the player sees two or three threads of a computer program written in C#. He must then step through the program, performing context switches as he deems appropriate in order to demonstrate that the program contains bugs in its parallelism code.

For example, the player might simulate an execution order such that two threads enter a critical section at the same time or that results in a deadlock.

The game won the 1st place at the hackathon. In addition, we won two auxiliary prizes – Improbable‘s prize for “the best gaming/VR hack” and Bloomberg‘s prize for “most interesting project”.

The game is programmed in Javascript.

We created the game at the age of 23, in 2016.

Play online:


  • Learn parallel programming by playing a game
  • A story-based campaign – slay dragons, master concurrency!
  • Over 15 levels
  • Over 6 different synchronization primitives

Fluttershy’s Hearthswarming Adventure

Fluttershy’s Hearthswarming Adventure is a text adventure game created for the Christmas of 2015. This is a fan game.

This is my second Windows parser-based interactive fiction. This means that there are no graphics to speak of – that takes place in your imagination. Instead, surroundings and events are described and you interact with the world by typing commands. But do not worry: It is not as difficult as old school games are. There is a suggestion system that will help find the commands you need and the game is set up in a way that you cannot truly lose.

The story itself is about the journey of Fluttershy to the depths of the Everfree in search of a magical artifact known as the Emotion Orb. She encounters animals, other ponies, obstacles and puzzles along the way. And in the end, it will be up to her to decide whether, and how, to change the Hearth’s Warming Eve festival for everypony, and for all time.

Remember that you are supposed to use a combination of the suggestion system and command typing. Usually, typing three letters of a word should be enough to eliminate most unwanted possibilities and then you use arrow keys and Enter to choose.

It is programmed in C# using the XNA framework.

I created the game at the age of 23, in 2015.

Princess Civilization

Princess Civilization is a 4X strategy game set in the My Little Pony universe. As Princess Twilight, the player controls several towns and gains more during play. The player progresses through a very long campaign separated in chapters building buildings, cultivating tiles, hosting festivals and exploring the surroundings. Also, friendship problems are built in that the player must resolve. Quests help move the player in the right direction. This is a fangame.

I made this game in C# using XNA 4.0 framework. I got the idea the night after watching the final episode of the third season of the show, Magical Mystery Cure, and wanted to do it as a tribute and because the final episode was so inspiring.

The game was created at the age of 20, in 2013.
