I participated in the GMTKJam 2019 and uploaded my game in here https://kneehatgames.itch.io/orbitone. 
Since I just worked the last day of the Game Jam I didn't have enough time to more than 4  basic levels.

• More sound effects
• Glow effect showing attraction
• Rotating and Moving Planets
• Visual Effects
• More levels

Here is an example:

Unfortunately it's not possible to upload during the voting time, so the updated version will be released only after that period.

You can test the game and vote if you want https://itch.io/jam/gmtk-2019/rate/463181.
