Too bad there was a bug within the menu! But with the link to the fixed version I could play it :)
The narration is nice, it makes it feel like you're guided through the game. I also like how you introduced the mechanics and updated the art, we had a similar idea for that. Nice submission, works well after the menu. Some sounds could have really helped to sell the movement, the guns and the levers and doors. And a win screen or something can make the player feel rewarded for completing the game, because if I understand correctly it resets the game back to level 1 after you finish the last level, right?
Overall a nice game, it works well in the theme and shows the progression of building a concept and prototyping!
