I wanted to like this game so much, but the lack of a save/continue feature, the inability to scroll the camera down to see what's beneath you so you have to make a blind jump and the frustration of some of the level design dropped my score severely. Otherwise beautiful graphics and story. 3/5
"for folks who got the door code... how did you do it?"
There's a post-it note on the map for the '0', in one of the rooms the light is flickering and a '4' appears on the floor, in another room '7' is faintly on a patient chart and in the last room an 8 is carved on the bed if you poke a patient chart enough to fall.
Way to win = Sniper towers. Start off with one in the middle of the map and soon as you can, upgrade to 2/3 stars. Save for another and repeat. Once you have 4 towers at 3 stars, upgrade them all to 5, throw a few range buff towers around them and then do whatever you want.
