This is fantastic, and the game I played the longest from this jam so far :) It was really smart to make the motherboard a cube so it rotates easily and lets you keep the components in a grid formation.
Some minor feedbacks:
- Would be nice if there were a couple sound effects for feedback - something when rotating a space and something when completing a level.
- There are some decorative elements to the motherboard which are a bit misleading when starting.
- Wouldn't have known without reading the page that the goal is to power "bulbs". Could they light up or something when connected? Maybe fans or other chips that have a led-style indicator would be a better fit?
- Showing the "puzzle complete" card immediately upon the connection being made is pretty jarring, especially in the cases where I was still making my way around the cube. Consider zooming out a bit and spinning the cube while some sound effect plays so the player is still connected to the environment.
- The music is great, but sadly doesn't loop!
- In your words, "making good puzzles is hard", but you did a great job of it! Please reply if you make more so I can play them too!
