game should include co-op in the future

I bought the game when I heard Ash Williams in it and so far I am loving it but I've looked online and can't find a way to play the Evil Dead levels and play as Ash, is there something I'm missing?? Thanks for the help!

Can you make the flashlight and torch ligh brighter? especially when the screen become red. Its already hard to see without the red layer. Honestly, my eyes hurt so much ... this is not good for my health ... cannot play this game for long I don't know how to solve this ... at least we can see the characters better ... giving them color highlight around their silhouette maybe ... or make the light source radius from the characters not dynamic without feathered edge (I don't know what I am talking) at le...

There is no more Ash for me to select on character screen? Is there something wrong or there is a thing I need to do to play as him again?

I am tempted, but would like to hear first impressions
