Ludum Dare 46: Staff Picks From a Record-Breaking Jam
Ludum Dare 46 wrapped up with a record turnout: over 13,000 participants submitted nearly 5,000 games in 72 hours, all built around the theme "Keep It Alive." The event’s long history and open-source ethos are documented in a feature-length documentary, portions of which were filmed at GitHub HQ during the 2017 GDC party.
From that massive pool of entries, a handful of games stood out for their polish and clever mechanics. Each of the titles below is fun to play and ships with its source code publicly available, making them ideal for study or experimentation.
Tower Defence of the Heart
Tower Defence of the Heart is a demanding but rewarding tower defense game from Terry Cavanagh. You defend a pulsating heart through 20 waves of enemies—skeletons, slimes, rats, and pink elephants in dungarees.

Cavanagh is also the creator of Dicey Dungeons, Super Hexagon, and VVVVVV, the source of which was open-sourced earlier this year.
Flock for Feast
Antti Haavikko’s Flock for Feast puts you in control of a growing flock of birds that a monster is eager to catch. Let your numbers dwindle and you’ll face the consequences.

What the Firetruck
David Fu’s What the Firetruck lets you unwind by fighting digital fires, a slight change of pace from the production fires you might deal with all day. As the meme goes, this is fine.

King’s Table
King’s Table by Petter Tuvnes layers chess and dungeon elements onto a tower defense foundation. It’s a surprisingly addictive combination—just watch out for the puns.
