That's okay!! I tried to explain it in the description as best I could when uploading the game but essentially both characters are playing on the same level, but from opposite sides! I had problems with collisions, so they're still on their own separate versions of the levels (but they are identical) otherwise I would've had them pass each other as they go through the levels! It definitely was designed for one person to play, so that it was challenging, but the option is obviously there for two people if they would find it fun :) really glad you enjoyed!
