Dev Diary #1
Greeting Competitors! It has been an exciting two weeks supporting the rollout of The Promethium Effect! We're thrilled to see players invested with hundreds of hours in the game, as well as great contributions in the forums. The Promethium Effect is only going to get bigger, and better as time rolls on, and you can bet we will be incorporating many of the requests we've seen in the forums. Here's what's coming up soon (in order of planned releases): 1. An in-game tutorial for new players to get them acquainted with the way the game works. 2. The ability to look at your attack history and the riches stolen from others. 3. Leaderboards. 4. Steam Achievements 5. Full controller support. Currently, a controller can be used to steer the ship in the asteroid field, but interacting with the interface otherwise relies on the use of a mouse. Thanks again for being awesome and supporting the little guys who just love making games. There's more to come! Cheers! -ZG TeamRead full article on Community Announcements (basher99)AnnouncementsOfficial
