I like the concept of having to work with another person to solve the puzzle, although there weren't many clues in-game to help me understand that. I found a bug with the chess board, as well-- if I click a piece and then spam a bunch of tiles on the chess board, the piece starts flying off the board. Although, bugs are to be expected, especially for a game made in only 3 days. I'd also like to point out that the music and graphics are very pretty.
Good job! :)
