Ludum Dare is a somewhat frequent competition where the aim is to make a game over a weekend in 48 hours. The game is then uploaded to Ludum Dare's website and the games are voted on and a winner is declared. After a while, a game jam branched off where there was no competition, just to make a game in 72 hours. My entry to the "not-competition" was a game called Mare Imbrium

Mare Imbrium is rogue-like game based on DoomRL (even has some sprites taken from it...) Where you play as a schoolgirl and have to save Mars from killer robots by shooting them - not the most usual combination. This was entered into the 28th Ludum Dare where the theme "You Only Get One", which is quite a vague theme in that you can generally apply it to pretty much any concept. Thus applying it to a rogue-like and it becomes You Only Get One Life - when you die you start from the beginning of the game. There are only three levels, I forwent having procedural map generation because I wanted actual game mechanics and I had a feeling if I went for procedural I wouldn't end up with much of a game.

The first and second levels are pretty easy - make sure to stock up on health! The third level is pretty difficult, a good tactic seems to be to try to get the bigger robots to shoot the smaller 'cannon fodder'. The game is very flexible, majority of things (items, enemies, maps, weapons) are read from CSV files so it's very easy to change details on the fly.

Source code is on GitHub. Bit messy due to lack of time!
