Maybe I should make a text-based game like The House Abandon ;)
I absolutely loved that game!!
Thanks for the valuable input, RainbowRat.
As for visual cues, there was rain actually implemented :D

You can see it after the third or fourth screen ;)
There was a gunshot visual as well, somewhere at the end
Maybe I should have added MORE :D
But I guess as others have mentioned, the contrast must have been a problem. :(
I think it's time I ventured more into 2d/3d games for my next jam. ;)
