Two Many Steps
Co-op puzzle solving, but the partner is just you from a few seconds ago.
About
Two Many Steps is a single player puzzle game with a co-op shaped hole in the middle. Every level needs two of you to finish, but you're only one person. The fix is the Replicator. Walk around, hit switches, do what you need to do, then trigger the Replicator and a clone spawns where it's placed. From that point on, every move you make, the clone makes the move you made earlier, in the same order. So your past becomes your partner. The puzzles open up from there. Stand on this plate so the clone can walk across the bridge, then jump off so the gate stays open while it pulls a lever on the other side. The whole thing lives in a clean, minimalist sci-fi lab with grid-based movement, so every step is something you can map out in your head before you commit. If you've ever wanted to play a co-op puzzle game by yourself, this is that.
