The Game Jam Ludum Dare 50 is over and the overall winner appears to be Claustrowordia, and it turns out it actually is a great crossword-type game.
You're given a basic starting board with a few letters filled, and a few letters of your own to place onto it. The difference here is that you can place your letters anywhere. It's a clever little tweak to the usual word-game and it's pretty amazing that this came from a Game Jam, made solo in 28 hours. I've played quite a bit of it, and it supports a few different languages too. All languages play the same, it just changes the dictionary and word definitions used.
Honestly, it's always amazing to see what comes out of a Game Jam like Super Hot, Surgeon Simulator, Broforce and a great many more.
