Here are my favorite games I've seen in this LDJam:

• Drone Supervisor: Puzzle game where you have little robots gather resources and build stuff.
• Lights Out: Puzzle game where you build up the power supply of cities. Includes little drone with snarky comments.
• Mr Mayor's Energy Crisis: Power management of a little city where the general public hates you no matter what.
• Gradient Descent: Just beautiful.
• Lionel's Weekend: Find your way out of a dark warehouse. Sound is very important in this game.

Although most of them have enough votes, give them a try!
