That was fun, I have the menu music stuck in my head and I really like the art style^^
I found mainly that it is RNG as to whether it is actually beatable, maybe the beer keg needs to have a bit more in it? or maybe it could still fill up even when you're ducking? I also found when axes fly quickly from the right it can leave you with very little time to react.
For variety, you could maybe a few more one-liners like the one where they say "this guy could even drink Thor under the table" because I found at least for me that "SKAL SKAL SKAL" got repetitive quickly.
I also couldn't find any easter eggs :(
