Looks good, feels good, fun concept, love myself some building in a game! I especially like the sequence where the great one arrives, nails the atmosphere very nicely. I also liked the flock of birds, and the birds occasionally settling on the roof, and the fact that one gets rid of pieces by giving the to the birds rather than the more obvious solution of throwing them in the sea. Very nice touches that greatly enhances the sense of polish. Good work for sure, with just the right amount of scope for a jam entry.
Some nits: the controls were a bit flakey, I was frequently be unable to pick up the pieces from the tentacles, clicks just didn't seem to register. Same with dropping off the unwanted building at the top, nothing would happen, with no explanation. The latter issue served to aggravate the problem that roof tiles would stack up from early on, frequently leaving me with only a single non-roof tile to pick from. Maybe tweak the frequency as the height increases?

Thanks. Gifting things to the crows was a last minute addition, before that you did throw them back into the ocean. I'm glad you liked that change.
That is all good feedback, thanks. I had thought about changing frequencies based on what blocks are missing/already in the castle but I never sat down to do it. I think you're right that it would be worth doing that to make the building process feel less frustrating.
