I just finished my second game for this competition! Not for Ludum Dare in general, but for Ludum Dare 38. The idea we (@olf09 and I) had first seemed OK, but after 1.5 days of programming and creating graphics and music, we noticed a slight problem: The game wasn't fun to play at all, so we decided to stop.

Things we did wrong: * Not designing the game fully before starting * Planing very little time for the idea (after ~2h we wanted to start creating) * Creating a game that doesn't give the player many different actions, and that was not very challenging to play

I then went on to think of ideas I could create alone in the 24h I had left. I came up with my new game World Tetris and now even have some time left (I only spent about 7h making this game!).

Don't underestimate how much time you can save with every minute of planning and designing!
