Damn, that little puzzle in the main menu actually took me one minute to solve, and later I found out that I should just click the letters in the title...
This is a very unique and brilliant idea! The ability for players to edit the level layout means that this game is not just a platformer but in fact, a combination of 2 genres of games. And this creates so many possibilities. Nice work! I love the music by the way. The levels are all pretty well-made. Really a fantastic work for 48 hours!
