That was incredibly enjoyable, many thanks to all authors and organisers! A few comments on each round:

Round 1: All of the puzzles were very nice. Especially liked the Yajilin, Kakuro and Pentominous.
Round 2: The compass was a really stunning puzzle. Statue Park felt over-valued.
Round 3: Tough round; had quite some difficulty with numerous puzzles, including the domino search which I ended up effectively brute-forcing. The Kurotto was excellent and I also enjoyed the Aquarium quite a bit.
Round 4: A fun, different round. Hard to pinpoint favourites here. Was rather lucky to solve the 'three steps' puzzle in about 30 seconds.
Round 5: A bit annoying to solve on paper; ended up having to resort to coloured pens, which ended up working ok. Perhaps it's fortunate that the puzzles here weren't too difficult... I really loved the concept though!

Thank you to organizers Priyam, Rakesh and Deb for putting together IPC ! Fantastic set of puzzles ! Can't imagine the amount of work that must have gone in the background to organize another week of contest and special applause for that. Thank you to all authors too for creating amazing puzzles !

My story of the day was wasting the last 10-15 mins of each and every round by jumping from puzzle to puzzle or getting stuck on a puzzle. It started with Rassi Silai in Round 1 where I had 17 mins when I approached the leftmost region having 6 turns and could never get it to work . Spent about 15 mins on that and still couldn't see how to place it.

My favourite of the day was Ayeheya Yajikazu (100 points) from Round 5. I simply loved how the logic unfurled in that. Will look to solve the leftout ( and that's quite a few) in the coming days.

Kishore
