The framerate didn't take me out of it at all- as a stylistic choice, it fit with the environment and the animation style.
What did take me out of it was the muffled and echoey audio quality. At times it was difficult to understand what they were saying, especially when it was low-energy mumbling. The acoustics of your recording environment played against you in this one. It sounded claustrophobic, which was in stark contrast with the characters being outdoors, in the open, surrounded by swamp and Ogre house.
Obviously a better quality mic is over the horizon, eventual when money can justify the purchase. In the meantime, there's a lot of steps you can do to mitigate the audio quality issues.
If you have a walk-in closet, with both ends flanked with hung clothes, that acts as a budget-friendly sound booth for when you're recording lines. Lots of folks do it. In addition, to avoid reverb from the ceiling, they'll hang a thick blanket overhead (not touching the actor or microphone) to absorb further reverb. I've also seen people thumbtack egg-cartons to their walls, tiled out, as a super-cheap soundproofing measure. But, you can buy the real deal sound-proofing foam for cheap, and then you can affix it with multiple 3M double-sided adhesive strips, or (what I recommend) liquid nails from the hardware store. The tubes that look like toothpaste are easier to apply than the caulk gun, but the caulk gun liquid nails are much more long term. While they're drying, you'll still want to affix them into position with thumbtacks so they don't try to peel off while it's still wet and setting.
Audacity is also a fine recording software, as is Reaper (trial version, you never have to pay for it), however, audio-processing isn't the issue. It was the mic-quality in tandem with environmental noise.
Other than that, the short was funny. I'm not really a feet guy, but that's just what makes it more ridiculous to me. Keep up the good work, and lemme know if you need a voice actor for one of your skits, I'd be down to help.
