I really liked the demo; it was one of the weirdest games I have played.
The only thing that I didn't quite like was the fact that the main character is always running so fast that it almost feels like you're playing as Sonic the Hedgehog.
And don't get me wrong, I do like that speed for certain parts where you definitely need it, since this game has a lot of platforming sections. But there could be a walking speed with the option to press "Shift" to run like in this demo.
