Awesome, your optical illusions are really cool. The moving background gives a sense of actual space movement. I love the music and the llama is cute!
At first I didn't know what to do though, but thankfully the restart is very fast, so I figured it out eventually.
Did you make everything yourself!? Those squares are awesome! I like how you show the ones that are coming so you have some preplanning to get there because you fly so slow. Very tactical.
Saving is awesome too!
The only hard part I had was sometimes I would fly to far and the coming square is off-screen.
