Hi!
Orion Knight was a blast to play for me! I loved the intro cinematic and the smooth writing out of 'Orion' in the menu. The stars for knight didn't quite hit that same mark for me, but I can totally see where you were going with it.
The idea for the game itself was good as well! The controls felt a little janky at times (mostly jumping and air control), but once I got used to that it was all good. Connecting the stars and seeing the final result was very satisfying.
Loved the choice of music as well!
Your healthbar could have used a bit of a paintover, but it didn't take away from my enjoyment exploring the stars!
