Which are your favorite puzzle games so far? 

First one is this  https://allalonegamez.itch.io/connect-all-the-bots , gave me a nostalgic feeling with gb art and sfx. Game felt complete, I didn't find anything missing in it. Level design was complete and easy to follow.

Second one is this https://petpumpkin.itch.io/handshakes. Nice concept, trickier puzzles than the first (at least I had a more difficult time than the first). More complex mechanisms than the first one. 

Both of them felt really good. However I still haven't played all the entries so if you've played a cool puzzle game you want to share go ahead.

I loved handshakes, it also had me laughing so hard while playing it. The concept is so goofy and fun to play and I actually got stumped a few times. To me the best part if a puzzle fame is the "AHA!" moment and I felt that a few times when I finally figured out how to beat the level. 

I have bot tried connect all bots yet.

If you havnt tried Shape Theory that game feels very polished and is quite challenging. I really liked that one too.

Grid-based puzzlers are always my thing

Missing Parts.

FACE 2 FACE.

SHAPE THEORY

my favorites in this jam and great puzzles and level design too.

Thanks a heap for the shoutout :)

It's already been pointed out, but John's puzzler I liked a lot.

One of my favorite puzzlers was Worlds Collapse https://itch.io/jam/lost-relic-games-1/rate/1576843 it presents itself really well, has some nice aha moments and a cute little story to go with it, definitely would recommend a try.

And it's pretty light on puzzleness but Dark World has a really great atmosphere https://itch.io/jam/lost-relic-games-1/rate/1579917

Out of the ones I've played so far, Our Galaxy is really cool! Just played that one. Also, Circuit Breaker was pretty decent too.

Handshakes is excellent for a jam game. Fits the theme to the point, the puzzles are great. I’d recommend it to anyone who hasn’t played it already.
