Thank you for the feedback! I'm sorry for the frustration.
Indeed, in the current version, it can be quite challenging not to crash and it takes some time to get used to the controls. We're already working on improving the control system and the camera, and by the end of the jam, there will be a first update with these fixes, as well as adding the WebGL verison.
Additionally, we're considering releasing a more complete version of the game later, with a difficulty progression curve and many new features, so that everyone can enjoy and explore the universe!
