That was great, thank you so much for the contest!

I had my expected couple of hang-ups, worst the one where I was convinced the Slitherlink couldn't be unique in the top right corner. Then later I made quite a big mess of the bottom left corner of the Suguru, reliably running into contradictions with the Star Battle below and even starting to doubt the rules (should I be allowed to swap the two regions??). Finally once these were fixed, I started to feel sure I was on the correct path and things fell a bit faster with some more intuitive solving.

I'm not so sure what to think about instant grading for this kind of round. It's quite a help to have your partial solution confirmed correct. I think that encourages less rigorous solving because you run less risk of guessing yourself into a corner where you don't know how far you have to backtrack.

A great contest! Shame that I wrecked the solve.

I thought the gradual grading made the solve immensely less stressful and is generally a great thing to have. However, 90-70-40 penalty system may allow solvers to do thing like checking all possibilities for Spiral Galaxies without caring about the coloured regions. (I accidentally did this, mistakenly assuming that Spiral Galaxies was unique without influence from the other grids)

forcolin already pointed out that reloading resets the timer. When I also accidentally reloaded, I noticed the "Password for Puzzle Booklet" changed to 1351634143 (first answer key to Tripod Sudoku). It seems reloading while running the contest causes much trouble.

Edit - Muhorka pointed out that it's my mistake, I tried entering that solution in the Fillomino answer key :(
Can I still request to claim?
Thanks.

What a fun contest.
Brilliant idea for a big puzzle - but I do feel the answer keys and the instant grading format allows guess-and-check over solving logically.
A wrong assumption in Slitherlink ruined the last stretch for me and I couldn't finish in time.
I knew Yagit was my weakest puzzle going in, so it was not surprising that Yagit and the two bordering puzzles were ones I had left.
Thanks for the puzzle!
