The game is simple to understand, but demands precision, especially in later stages, which I always like about games like this! I also like the choice of music at it really fits the game's atmosphere. There is a minor bug though where you can always see the 'ORBIT' sign while in fullscreen (bottom left of the screenshot), though that likely isn't the case for everyone due to different screen resolutions, but it might be something related to the scaling settings for that sprite specifically as it doesn't happen with the other two signs.
