I got the 3rd ending, actually paid attention to the controls dialog, and then got the 4th ending :)
There are a lot of actions we can do, maybe too many to introduce at once… I get that the interspersed buzzing is better for flavor, but the text that teaches these actions could be better spaced.
Also, the way to advance the menus should be uniform (click for starting the game and E for advancing text later on is confusing).
Still, good little game and I love the idea of multiple endings (I was going to do it if I had finished mine!).
