Pretty fun game and it looks nice too.
The only problem I see were the illogical solutions. How do they find the blood in your stomach? Why can you only hide the gun in one specific cabinet? Why can't you fully close the door so that the hand doesn't poke out of it. Due to these inconsistencies the game was purely trial and error. Of course that's not necessarily a bad thing.
But regardless it was a solid game, and it felt satisfying to win. Good job!
