Just played Bullseye for a few hours, and I must say, I'm very impressed with what the team has achieved. I've been following ZPS for a few months, but playing this "demo" finally convinced me to the drop the 40 bucks and support you! Keep it up!
Regarding BE, I was positively surprised by a few things. First, the handling of the weapon. Through the first few challenges, I was surprised by how the weapon behaved when I was shooting at cardboard figures, even when looking down the sights. I thought I'd get a headshot, but I didn't even hit my target. I really enjoyed that, because it proved to me that I couldn't just expect how to fire, I had to actually aim. xD
Second, the "penalty" when not manually reloading in time. Very nice feature, however, I thought it to be a little late when only having 5 rounds left, because I found myself not being able to manually reload in time. Maybe increase the round alert to start beeping at 10 or 15 rounds left?
Oh yeah, a minor thing: I don't know if it's final or not, but when putting on silencer or scope, I liked that the weapon just went out of frame and came back with it on, instead of a lengthy animation that put it on. It might just be me.
If I didn't have a WoW raid tonight, I'd probably keep playing this addictive shooting range demo until some time tomorrow. Thoroughly enjoying your work, ZPS! Keep the demos, and of coures, the game coming!
