Puzzle design...
My game mechanics are all up and working, but I'm no good at designing puzzles. I have one puzzle that might be clever, or it might just be unfair and obtuse.
Current mechanics are:
- Time loop that creates clones.
- Switches that open gates (and close some other gates).
- Boxes that can be pushed and used as a platform or to hold down switches. Multiple clones will push the box faster than just one.
- "Clone gates" that can be traversed by the current player, but will block time clones.

At least I have composed some catchy chiptune music.
