I found a big problem with this - I noticed that the longest answer is very often the correct one, which kinda ruined the game. Even though I didn't want it to, it started affecting my decision-making. Luckily, I only noticed this around question 85, though those are really the tricky ones.

Good news for the project is that I think you can easily tweak the LLM to generate better alternatives.

I got 89/100, which extrapolates to 72,700. As a non-native speaker, I'm quite happy with that.
