A really good proof of concept here!
The game is very minimalist, but it already has a nice feel to it. The GUI is clean and works well, and I think you have a solid foundation to build upon.
I did notice some performance issues when playing in fullscreen. When I kept the window smaller, the game ran smoothly, so there might be something worth looking into there. 😄
My only small complaint: the crosshair feels a bit too tiny for me. Making it slightly bigger would improve visibility and make aiming feel a little better on my big Monitor. ^^
Other than that, I'm really interested to see where this project goes next! I’m especially looking forward to things like juicy sounds, more feedback, and those little details that make a game feel alive. 🔥
Great work, keep going! I’ll be following the progress. <3
