I like the idea and approach to the theme, the art is top-notch, and have a story company with the gameplay, it's a very nice surprise and a hidden gem, I can see this as a complete game.
However, as many people say, there have lots of game-breaking bugs, I played until day 2 with multiple resets because of some stupid collision problem, like the image below (I thought I put the bullets into the box but nope, and now I can't get the bullet again)
Besides the manual text, I think that the "bullets number on the clips" is also hard to read with white text and a similar yellow background wall, adding a black outline on the text will help it more readable.
