idea is good but it lack tutorial at least somwher writen how to play the game, also you can go trought the most walls, oh also when you die you just respawn whitaou lossing any progres (sorry for tragically bad grammar)
For some reason the start button don't work, all others work, so maby it's bug or you just put her no't working version. But from description it sounds like cool game.
This is very fun experience, but I think that there is bug wen you randomly start to see back of tor the car and granny just stares in to you whit her cold eyes. (Sorry for bad grammar )
