World of Colorcraft, UT Game Jam (2020) / Ludum Dare 47

Warming up for Basic Game Development course homework (Tallinn University). We got a lot of help from Tartu Art School 3D students.

Gameplay meets color theory in this 2D game in which the colors of the world are in danger of being swallowed by the Evil Black Hole. The Guardkeeper of all the colors in the world has become old and feeble and the task of saving the colors has been transferred to his apprentice. Can you collect primary colors and take them to the Guardkeeper in time to produce secondary ones? How about tertiary colors, or even more? Embark on a journey looping the color wheel to keep peace and harmony in the world of colors.

Virtual Geometry, APT Game Jam (2020)

The game helps to understand how to describe 3D-objects in 2D-medium and interpret (recreate 3D-objects of) 2D-drawings, how to draw multiviews of any object, explore sacred geometry through different time-critical tasks. Beside tasks students can interact with topic-related gadgets. Planned as VR Game, but executed as PC version. 2 years later, this project transformed to Geometry Maze, with which I work together with my colleague in Tartu Art School right now.

Best Design Price.

Team: Lasma (Creative/Arts), Rhea - (Marketer), Siim (Creative/Arts), Martin (Developer), Enlik (Software Engineer), Aigi (UI/UX design), Elina (High School Student), Karina (Product Designer). 

My role: Helping to develop game mechanics and content, which took us from all the first 40 hours to figure something out. I was working with interaction part (interactive lightning according to player figure placement) of the physical prototype, because I have some earlier experience with electronics and microcontrollers. But we abandoned that part and reduced it to very mechanical level...only art (thanks to our Latvian teammembers) , no robots :)

Logopuu, Garage48 EdTech (2019)

Desktop/mobile app

Logopuu is an interactive web-based learning platform made to support Estonian children’s speech and language development. It’s main goal is to help parents and people working with children detect, prevent and overcome speech and language developmental problems as well as help those who need systematically organized and science-based information about Estonian language. 

People with speech problems don’t get help and therapy (too long time to get an appt. Solutionplatform to fill time with useful tasks (games, exercise videos, materials between visits). Technology and speech and language dev platform. 

Team: Nikita Tikhomirov (marketing / team lead); Jane Meriloo (education expert); Kati Mäesaar (education expert + business mind); Polina Minaeva (designer, animation artist); Siim Soonsein (designer); Serhiy Krynytskyy (product manager); Maris Põkka (education expert). 

My role: different skills and experiences where needed during this project. I think the most interesting part was to make an animation of users’ game experience, animating a story with speech exercises. We had a talented animator (Polina) in our team who prepared character sprites but unfortunately had to leave the country during the event and I continued her work as editor to put the animation together with a video editor (After Effects), which I had to learn on the run :)

CQR, Riga IFF Goes VR (2019)

VR game

1st Price.

Imagine how cool it would be, if going to school would mean only experiencing nice, predictable environment, welcoming attitude and interesting lessons? But reality, unfortunately is far from this – every day thousands of children in Latvia experience stress and other aspects of behavioral disturbances, not being able to swiftly adapt to the new environment.

Not only going to new places, but simply attending school is a huge problem, especially for children in the Autism Spectrum.

The Autism Society of Latvia is aimed to encourage the design of a new approach, that would aid to get used to new environments though immersive tech – virtual reality headsets with specific social scenario, teaching how to overcome stress in a fun and entertaining way. (Autism Society of Latvia)

A solution to children with autism spectrum wins the virtual reality hackathon

Team: Marina Petrakova (project manager), Lukass Dzalbs (developer), Siim Soonsein (3D-art), Edza Polis (3D-art, testing), Aivars Ivanovs (3D-art), Eriks Dou (developer). 

My role: Level design (helping out Aivars), but also helped working with game actions and challenges, preparations for the pitch (fact search, business model, roadmap).  This was my first game jam, I didn't have any experience, so I tried to help out with anything I can. That event triggered me to start learning game engines :)
