LD 44: Bloodcurse Recast

Hi, It’s Ludum Dare time again! Time to ask friends to meet for a weekend and develop a game together. This LD was the first one for Tim, a 2D artist I know, and also Nils joined for designing and balancing and we got some music from Partick, who already left Darmstadt but managed to […]

7LDR: Rogue 2048

Welcome! There is another game jam entry of mine for yet another jam I have never participated at: 7DRL, the 7 Day Roguelike Challenge where you can pick seven days to create a roguelike. I did team up with Martin who found me on a Discord game dev server and we tried our best with […]

LD 37: Game Jam Simulator

Hi, once more its time for a Game Jam! It’s Ludum Dare 37 and the theme was ‘One Room’. Chris and I quite committed to create a game about managing your own game company. It’s about finding new talented staff, motivate them, start and sell the right product suited for your team and manage your […]

GGJ: Sofa King Good

Hi and welcome! This time it’s something special: After several Ludum Dares, I finally have participated in a Global Game Jam. That’s something completely different – at least if Game Jams are something usually for you. For LD, I prepare my desk, invite friends, go shopping and do not interact with anyone for a weekend, […]

LD 43: One For Another

Hi there, Sacrifices must be made! That’s a fact – at least for everyone playing Ludum Dare 43 games since that’s the theme of the jam this time. It’s not the first game jam for me, but still this time its something special: No friend of mine had sufficient time to join me this weekend. […]

LD 40: A Hero’s Burden

Hey hey 😀 Once again, I have a nice game jam entry of mine for you: A Hero’s Burden made in 72 hours for Ludum Dare 40. The theme was ‘The more you have, the worse it is’ and this time we finally did not take the theme by hard. Instead of having resources or […]

Epic Space

Welcome 🙂 Today I want to introduce Epic Space, a mobile two-button lander. Originally, this project started as a demo project of mine to show friends of mine how to create games with unity. I’m super happy that this demo project did well and developed into a real game that actually is fun to play! […]

Tristoy on Steam

Hi everyone! I’m proud to tell that TRISTOY has been published on Steam. It’s a two-player coop game where you and a friend have to escape a mystic prison on an island. Set in a modern fantasy setting, TRISTOY has action-based combat, nice puzzles, branched dialogs and replayability. As originally implemented as a local multiplayer […]

LD 38: Expand and Exploit

Hey hey 🙂 Expand and Exploit is the third game I’ve done in a game jam. Together with Chris, a good friend of mine, I took a weekend to build this game. The game is about conquering the sky with all its planet. There are three serious problems one has to care about: – There […]


Hey there, This is TapTrixx, my one and only Android puzzle game 🙂 I’ve originally developed the idea with a friend back then in the first semesters of my computer science studies. Sadly, lectures made us never really publish the game. A few years later I took some time and reimplemented it from scratch with […]

LD 35: Project D.A.S.H.

My second try on a game jam. The theme is Shapeshift and we maybe took it a bit too literally: You control a little character that can morph into three different shapes: The green, the pink and the blue. Based on a bullet hell and rock-paper-scissors, the game is an interesting hybrid.
