I'm so sorry, my friend. I really wanted to play this game, but I suffer from 3D motion sickness. It was so dizzying that I couldn't keep playing. However, I'm amazed that you implemented a 3D game incorporating machinery. Did you build the physics engine yourself? That’s impressive.
The way the arrows follow a parabolic path was very striking. I personally love archery, so I noticed a few things. Usually, when I shoot in windless conditions, I look at the target and aim slightly upward to get a feel for the distance. In your game, however, long-range sniping is quite a challenge.
Also, from my experience firing a crossbow, the trajectory isn't quite as steep as it is here. It’s a bit more level before it suddenly drops off. (Crossbow parabola: ㅡㄱ, Bow parabola: ㅅ) It’s hard to explain with just text, but those symbols are the best way I can describe the curves. Truly a brilliant idea. I'm leaving 5 stars for your innovation!
