This whole thing feels like one big RNG-fest. The only way to make progress is to have good luck. If you buy an ammo clip, that gives you 6 shots for 20 xp. A normal duck gives you 5 xp, a miss in the relevant level range takes away 1 xp, and an accident in the relevant level range takes away 4. Doing the math, this means that, in order to make progress, you need to hit at least 5 out of the 6 shots, or get lucky enough to find a free ammo clip or a golden duck. This is unrealistic to expect when the accuracy within the relevant level range starts at 55% and only goes up to 58%, and the chance of a golden duck or a free ammo clip seems pretty small (though idk the actual chance). Thus, the only real way to progress seems to be getting ridiculously lucky or a LOT of waiting, neither of which seem to entirely fit the "Fun" category.
