Guess everyone wants to make their version LOL. As for your points:
-Yes, there is currently no indication of the CPU's target, but that'll be featured in the animation update.
-I have stated on the page that shooting yourself is useless(I wish ppl would read the whole thing so I don't have to repeat myself TwT) until the energy system is implemented. As for the suggestion of Buckshot Roulette's chamber system, I decided against it for the lore, as the inflation gun is a piece of scrap that doesn't work 80% of the time.
-That's something I oversaw. The text and image are supposed to appear over the black overlay, but my dumbass put the overlay on the front layer and forgot to put it back. I'll fix it in the next update where I have a proper title screen.
Thanks for sharing your thoughts! I find it good to hear from others, whether it's just a compliment or constructive criticism :D
