Hi, I’m Tamás Karsai (Spidi) a solo game developer forming “Magic Item Tech”. I used to grind for magic items day and night, now I’m building games using technology fueled by them 🙂 . Terminal craze: cats, game development, games, movies, toon & anime, comic books (in that order).

If you have any feedback or problems to report or you would like to chat you can reach me at:

Mainly by e-mail, frequently on Twitter and Facebook or rarely on Reddit

Documentary, open development

I’ve been blogging about game development for years now and when I started my full-time venture I also dabbled into video log production. So I documented a huge part of my journey. A big motivation for doing these “side” projects is to give back a little to the game development community, since it helped me countless times before! I also enjoy writing about my progress and I like producing these videos. I really hope others find it useful.

I organized these vlog entries into a playlist. The first few videos are noisy and much less organized than the new ones, but I became better at making them over time 🙂 .

Freely cruise around the Magic Item Tech Youtube channel! I have some game development technology showcase videos about the frameworks I use and some tutorialish stuff too besides the game trailers and the vlog entries.

You can also follow my daily development progress on my Trello board.

And if you favor Tumblr over WordPress I post my less text-heavy media content there + AMA is active.

Oh and if you love GIFs and screenshots look no further, cause I love creating them: GIPHY & Imgur.

Mission statement

I formed my thoughts around two key aspects, closest to my heart, which tell what kind of games I’m trying to deliver and how I approach their realization. Turned out to be a bit lengthy, but certainly focused, feelings and goals alike, which define the game developer I am.

Thriving to create diverse games, designing them by their mechanics.


The game industry is a wonderful place by allowing a vast array of different experiences to coexist, and has a respectable audience appreciating the whole spectrum. Be it a game about shooting bad guys, or a game about solving puzzles seeking to train the mind, or a game focusing on evoking a certain emotion.

Design by mechanics

Games first and foremost are about their mechanics. This is the core of the medium. It is interactivity what separates them from other art forms and media. It is the ways players are able to interact with a game, which defines them both as an art piece and as a product. I’m looking to come up with interesting mechanics before anything else, than designing the actual games around these mechanics to discover the full potential of these ideas.

Cats, living, working

I live and work in Budapest, Hungary in a cozy flat we rent with my wife Ágnes. Currently game development is my full-time pursuit, trying to make a living and building a sustainable business. We are also the owners of two lovely cats Judy and Helena, although we always refer to them as our bears 🙂 .
