To be fair, I'm not sure I know exactly what I should do and how to do it...but it feels like a very fun toy and I spent long minutes having fun trying to go down the hallway!
The gun shots are perfectly synced too, which I greatly appreciated :)
It's a movement "shooter", if you're moving fast you're probably doing it right. The level design is linear, so just keep moving forward, there is no wrong way to go other than backwards.
