I love this game for two main reasons.
First, the aiming mechanic was challenging — especially with moving targets — but in a way that made me want to keep trying even when I failed. It felt rewarding to improve, which is a great design choice. My only critique is that I wish I could see the bullets to better gauge travel time, which would help fine-tune my aim.
Second, I think you’ve built a fantastic foundation for a first-person shooter. This could easily serve as a “boot camp” or training level leading into a larger game. The backstory you wrote — about life throwing everything at this character, and him pushing through anyway — is compelling and could be expanded into a full narrative.
I also loved the ballistics aspect, where the timing of shots depends on distance and target speed, adding a subtle but satisfying layer of skill. Overall, I love the concept, the storytelling, and the mechanics. Well done!
