I thought it was fun, but I think it's got some kind of memory leak? I got to round 52, and it crashed, whereupon I checked task manager to see it had used up every last bit of my RAM. Specifically, it was using 24,681.4 MB (of my 32 GB system). This was my second time playing, this time with the AK-47. Not sure what my score was, something in the teens of millions.
I do appreciate that this is a straight homage to Duck Hunt. The mouse controls are as smooth as you'd expect from an FPS or aim trainer. Options are barebones; I wish there were an option to make the targeting reticule contrast better against the bright sky. (The sky looks a fair bit brighter than it does in the store pictures.) The way the ducks flop out of the sky but retain some/much of their prior momentum, makes for a great visual style. If you press E to skip ahead quickly, and aim well enough to shoot 2-3 ducks in one shot, it gives the impression of duck fireworks.
The game's biggest flaw is that the difficulty ramps up soo slooowly. For a halfway competent gamer, it takes forever for the game to get challenging. But some of the other reviewers are wrong: the ducks DO get faster, and it IS possible to get a game over. It just takes a LOOOONG time. And it's not clear to me exactly what the game over conditions are. It's a vibe; if you feel like aiming at ducks for an hour plus, this is a game for you. Unfortunately, I just don't think this is a good difficulty slope for this kind of game. It should get hard faster, or at least have an option to enable faster progress (with a different score tier, or something).
I've come across one other notable glitch. You reload your gun in between flights of ducks, which you can skip by pressing the E key (or use a controller mapped to E). Once, on round 45, when I was skipping pretty quickly between ducks, it skipped to the next flight of ducks before I had taken care of the previous one. It did a few flights in succession like this, so there were maybe as many as 8 ducks on the screen at one time, and I was running out of ammo while still missing the incredibly fast birds. I got a fly away, whereupon all the ducks left and it went to the next flight normally.
Plus two more non-notable glitches! When skipping fast into the end of a round, your dog can still be repeatedly jumping up in the background while another of your dog appears in the foreground to start the next round. And (maybe this is intentional, I don't know) sometimes your dog appears in mid-air to jump, making it a slight distraction next to the flying ducks.
A very common pattern for the ducks is for two or three to all fly toward the center of the screen and overlap in such a way that you can shoot them all in one shot. (In fact, they do it so often, one might be convinced at the beginning that this is the only pattern they fly in.) I'm sure this is a way to make it easier for the guns with less ammo, plus get through the ducks quicker. It feels cheap, even patronizing in the beginning, but in later, harder rounds, it is a lifeline. I'm not sure if shooting all at once gives a score bonus or anything, though it does play an overlapping sound so you can tell you shot multiple even if they're flying too fast to tell whether they're falling. I don't dislike this feature, exactly, but it could really be improved in conjunction with the difficulty to make it a more polished and widely-appealing game.
Ultimately, I don't exactly recommend the game, on account of the apparent memory leak and the tedious/unchangeable difficulty slope (not a difficulty curve, AFAIK). You may still enjoy it if you want to have a zen aiming experience for a long sitting. The price is right for that.
