how was this set played ?

$300 NL Live
Hero has 500$ behind, Villain covers hero. Villain is a donk and had made some horrible calls before and stacked off. Then went on a rush (hit straights and flushes) and now has about 1000$ behind.

Hero has 10-10 on the button.

Preflop: Hero raises to 15, Villain calls.
Flop (30$): 10d-6c-5s
Hero bets 20, Villain calls.
Thoughts: I want villain to call with any pair. maybe he hopes I have AK and am cbetting or maybe he has some overpair himself .

Turn (70$): 10d-6c-5s -8d
Hero bets 60, Villain calls.

River: 10d-6c-5s -8d-7c
Hero checks, Villain bets 100, Hero calls.

should i make the call here ?? I seriously put villain with 2 pair, and thought maybe he puts me on AA or KK or whatever. If he has a 9, oh well.
Is the 100$ a bluff bet or a value bet ?

I start betting the pot and stop bluffing against the player described.

As played, it's fine.
