1) Go here: https://flowlab.io/game/play/588397
2) When you press W, A or D the intention is the lander will move up, left or right respectively, and consume one unit of its 1,000 fuel per one press of any of those buttons. It does this as expected when you play the first time after going to https://flowlab.io/game/play/588397
3) Click "Open Editor". Click "Play" from the main screen of the editor. Again, it functions as expected.
4) Click "Open Editor" a second time. Click "Play" from the main screen of the editor. Now when you press W once you lose what looks like 20 units of fuel right away. Sometimes this happens on #3
and sometimes it takes until #4
of this list. I've included a screencast if that helps.https://youtu.be/hIzorMho2RU
