Our challenge, your solutions

Adjust artificial gravity to jump higher and achieve your goals

In this small proof of concept game, you control the radius and the rotation speed of a rotating platform. You adjust the centrifugal force exerced to the object that the player can move. This game is allowing children to play with the effects of gravity and to understand what this means to us.

Members roles and background

I’m a student of cultural and media education in Germany. My main areas are education and therefore free software (FLOSS), Open Educational Resources, privacy and media production. I also cooperate with the local planetarium in some projects. I learned game creation in a job for my university where I’m still developing a serious game for VR and Fulldome.

Solution description

I created a game as proof of concept to my initial idea.

The player controls a character located on a platform rotating around a center point above. Outside stars are visible and indicate the rotation of the platform. The player can try to jump onto several platforms that around him. But at the initial state of gravity, the player will not be able to jump high enough.

To jump more or less high, the player has to adjust the radius and rotation time of the platform, in other words: the player can change the artificial gravity. All three values are displayed on the screen in order to help the player to get a feeling for them.

For the challenge organised around the Luxembourg MakerBuzz, this solution can be used as part or in addition to the workshop "spinning colors" ( and motivate participants to dive deeper into the topics gravity and space travel.

Because the game is created in a pretty simple pgraphical mode and since it is made with the free game engine "Godot" and its visual programming, this is also a good starting point to use in workshops for 3D game creation with kids.

I would consider my solution successful as soon as participants playing this game start to ask questions about gravity or artificial gravity.

Solution context

In the workshop "spinning colors" (, participants build something to stir up water and create a vortex. The shape of the vortex is influenced by gravity, centrifugal force and other factors.

I wanted the participants to be able to experience artificial gravity without the need of (currently still) expensive VR headsets. For me, it was also important to only use free software so I don’t have to rely on single companies in terms of support, license or security.

Solution target group

My solutions aims at school kids that are older than 9 years.

Solution impact

With my game the Luxembourg MakerBuzz is able to cover the topics of gravity and space travel. It can also lead to new ideas for games or workshops.

I would measure the impact by counting ideas caused or influenced by it.

You have to reach higher platforms but can’t jump high enough? No problem, simply lower the gravity. But watch out, space is endless – Gravity Game

Solution innovativeness

In terms of topic, there are nearly no games covering artificial gravity that also give you an immersive experience.

Additionally, the game is meant to be completely adjustable by kids. This is achieved by using the free (FLOSS) game engine "Godot" and its visual programming ( This allows the player to change from consumer to creator without worrying about licensing or privacy.

Solution transferability

My solution can be used in different contexts. It mainly serves to introduce someone to the topics of gravity, of artificial gravity, of space travel or of game creation.

Solution sustainability

Because my solution is flexible and can easily be modified to the specific needs and only requires basic hardware I would call it pretty sustainable.

Solution team work

It was just me. In the future I would prefer to work in a team.
