Here's my entry for Ludum Dare 57.
The theme was Depths and my game idea was to make a mix between a Miner (the VGA one) and a Minesweeper. I did it in C and used raylib. I'm not happy about my code as I rushed things a bit but it is what it is. Actually, I feel good because this is the first time I've delivered a game in less than 48 hours (minus the programmer's time).
