The Two of You
This is a game I made for Ludum Dare 29, in 2014. In 2018, I fixed a critical bug it had, and one small related bug, and put the game up for download. I also finally recorded a walkthrough, including developer's commentary.
Be sure to play the game on the Easier difficulty, and if you do get stuck, check out my video on the game. You can press F4 to toggle between full-screen and windowed view.
