The style of this game is amazing, and the soundscape is good, relaxing. Obviously there's not much content to be seen just yet so you should work on a real gameplay loop for next time. I think you're cooking up something good so don't beat yourself up over it. I like the logo for the game too, I know you put a lot of work into it (and into the rest of the game). Just keep going
Oh, forgot to mention but the UI in the ammo/health and the tab menu is kind of hard to look at for me. I know it's the style of the game but you might want to consider doing something about it? But still save it for when you have more content though if people aren't complaining
