It's definitely not polished and has a fair bit of jank to it, but it feels honestly just kinda boring without any threat from enemies or any wacky sound effects or visuals beyond the finger gun and slwo moving bullets.
This game feels like there should be a gunshot sound of a guy just saying "bang" into a crappy mic, and enemies with a poorly drawn face on them or something. But instead it's empty levels with no real threat and the ending just zaps right back to the menu.
And I can see the argument that an ending like that and levels as they are would be SBIG, but to me just kinda feels hollow.
I DO appreciate the fact you had some level of tutorial in game though!
Congrats on submitting!
