EDIT: I figured out how to get past the part I couldn't get past, and, yeah... I'm just stupid. 99.99% of people could figure it out. I finished the demo and it's great. XD
Old comment:
Great game! Really, I had fun. I encountered Just a few problems:
1) I accidentally went through the wrong door and went to the VERY BEGINNING and had to replay the part I had JUST FINISHED after spending FIFTEEN MINUTES on it! That was a little frustrating. (I'm bad at video games and that's why it took me so long, but still...)
2) I can't figure out how to get past the VERY FIRST challenge that used the advertisements! I eventually just gave up, and I still haven't beaten it as of the time I'm writing this. I'm probably just stupid, but some indication on what to do from the narrator would be nice.
3) I couldn't tell what was in the foreground or background sometimes. Like, I'd run into a wall thinking it was just a wall in the background and fall to my death.
The game has AMAZING potential, and overall the demo is pretty well-made. Putting aside the fact that I follow the devs on YouTube, I'd give it an unbiased 9/10.
