This is a nice and clean relaxing gamejam game! I personally wasn't worried about the spike movement being telegraphed like some other players were? Not sure where that came from. Since you could just observe them at the start to see what their pattern was.
Everything works really well, my only *minor* complaint might be to let the WASD input be buffered just a little bit, so its a bit easier to time, or even let the button be held down.
Also for the theme, this is the first one I played where randomness does not play a part but it still matches the theme. Well done!
