Essence Ltd. is a start-up company from Sofia, Bulgaria.

We are a team of two, Andrey Glavchev and Kaloyan Zlatkov. We are passionate ex-gamers who want to express our own vision of gaming by crossing different game genres, innovation and commerce.

We are aimed at delivering high quality, free-to-play online games. Currently we are delivering applications for the web (including Chrome Web Store and Facebook), Windows PC and OSX (via Steam) and the major mobile platforms: iOS and Android.

Our pilot project is called Battlegrounds of Eldhelm - a free to play collectible card game.
It is heavily influenced by RPG games and borrows some mechanics and ideas. The result is a fascinating mixture of classic card collecting & duelling game with RPG elements.
The game features epic music and 3D graphics. It is translated in multiple languages and is available on the desktop PCs via all up to date web browsers at, as a desktop application on Steam for both PC and Mac, Google Play for Android and Apple App Store for iOS.

Currently we are working on a fast-paced, action/strategy/arcade game called Solar Coherence.

We are building our games on top of Our own back-end technology called The Eldhelm Platform, available as an open source project on github. It is a scalable and extendable application server designed for rapid development and fast deployment - developed in Perl 5. The Edlhelm Platform also features various front-end and back-end frameworks and tools written in Perl, JavaScript, Action Script and C++.
