Last year, PICO-1K Jam 2023 took place in September. I don't know if it will repeat dates this year. It's a bit different approach as 1024 compressed bytes is huge compared to just 500 chars.
And yes, resetting score when missing a putt is achievable in 500 chars. I can't remember why I didn't implement it. Maybe because I found it was too difficult to chain successes with no difficulty ramp in place or because I had plans to include sfx.
