Project Overview
Roll & Rock is an educational mobile game for which I created the graphics, sound, and music. Set in a vibrant, cartoon-inspired world, players join Joe, the enigmatic stonemason, as he journeys from Finland’s Saana and Japan’s Fuji to Australia’s Ayers Rock, Egypt’s pyramids, and finally Stonehenge – all in search of hidden gemstones.
Services Involved
Lasse Eronen
Education Entrepreneur & Scholar
University of Eastern Finland
I have collaborated with Eero since 2014 on multiple projects. He has proven to be an exceptionally creative and visionary thinker, both in graphic and musical solutions. At the same time, he is highly committed to logic and functionality, which has elevated our project execution to an excellent level.
Solutions created by Eero have always been delivered on time, and he has been highly attentive to the client’s needs. He’s an extremely reliable collaborator, and his contributions have been invaluable.
Marko Savikurki
QA Specialist & Game Developer
In 2015, I worked with Eero on the educational game Roll & Rock. While I handled the game programming, he was responsible for all visuals, music, sound effects, animation, and various production-related tasks. We later extended the collaboration to include the game’s official website, which Eero designed as well.
As the game programmer, I appreciated how carefully prepared and well-structured all the art and audio assets were. Everything was optimized and delivered in a way that made implementation quick and straightforward, which saved time and kept the development process smooth.
Having been involved in several game projects, I know how demanding it is to wear many hats in a single production. Eero managed that challenge exceptionally well, with a calm and organized approach that consistently led to high-quality results. Working with him gave me confidence that whatever we set out to build, we would absolutely get it done.
Since Roll & Rock, I’ve come across Eero’s other creative work, and it’s clear that his strengths in visual and musical design extend across a wide range of projects. I would gladly work with him again and can confidently recommend him for any role that demands creative quality, reliability, and attention to detail.
My Role & Contributions
The game, published in 2015, inspired me to release the music I composed for it as a standalone album. Many of the six tracks feature extended, full-length edits that go beyond what’s heard in the game. I also designed the album’s cover graphics, based on the game’s main character and assets.
The album is available for streaming on all major platforms.
