I just finished the 2016 7DRL Challenge. My game is called Bisbee’s Escape. It’s inspired by games like Dig Dug, Mr. Do, and Digger. Your only weapon is crates you can drop on enemies. But these crates have different effects for you to discover.
I didn’t have as much time as I wanted to work on it this year so it’s a little rough around the edges. But it’s playable enough and I hope to fix all the outstanding bugs in a later post-challenge release. Go check it out!
