Nice game buddy, I loved the idea and the game mood. There are just some bugs that need to be fixed, like when I arrive to the portal the game just freezes and I can't move anymore.
When a cutscene ends, it freezes the player, so you don't keep walking even if you're not pressing on the controls. If you get frozen after a cutscene, move in a different direction. If that doesn't fix it, restart the game. I'll look into that.
