I'm a huge puzzle game fan and just wanted to give a shoutout to two really good puzzle games I've played so far.

Robo-Power

Program robots using a loop of at most 4 instructions and direct them to drop a power box at the exit. The levels are really well designed and can be quite tricky. I also really liked the funny narrative that went along with the game.

Don't Be (The) Patient

An arcade style puzzle game where the goal is to find the sequence displayed on the bottom in the given grid. As you progress, the sequences get longer and longer. The game has some really nice audio; the jingle with each sequence you solve is really satisfying and the pulse gradually gets faster to warn you that you're running out of time.
