I tried playing the game on pc, and that's the screen that i was stuck in. By the way, my pc has a somewhat low performance, maybe it's related to me don't being able to play.
OK !
This means that something is wrong with the loading of the first video.
Do you have any particular settings on your browser regarding video playback? These are videos in mp4 format.
There's a good chance it's me who's done something wrong. But in case try with another browser to see if it works.
Keep me posted, if you want.
Sorry again.
