There seems to be a glitch where if you restart and click at the same time you will be at the start of Zone 2 with a randomly generated amount of crystals varying from 700-1000. This should be fixed, people can easily abuse this to max out stats quickly.
For all those getting "stuck" after putting the two chest luggage pieces together, there is a simple way to fix this. Put the two pieces of luggage together NEXT TO THE DRIVER. This will allow you to speak to him and unlock a new checkpoint. After speaking to him, press and hold R to restart at the most recent checkpoint. You will be unstuck and able to progress. Thumbs up for everyone to know.
I loved how the rooms transformed, I also liked the artwork. But it was pretty easy, finding that you had both the shake and reveal options and after finding an object you would find more points to regenerate the bar. Still great game. 5/5
