I've put The Diabolical Cult of Monsters on hold for a little while while I work on Super Retroids XD Plus.
I actually lost the source code for the original version of Retr0ids, because I didn't make a backup of it, so I'm having to start development from scratch. This is actually a pretty good thing because it's enabled me to make a much more polished game and do a few things better than they were before. The eagle-eyed among you might notice that the .GIF above is not of Retroids, this is a little game I have in development called Asteroid Mining Company, some of the code from which will be used to create the basis for Super Retroids.
Retr0ids has always been an Asteroids clone at heart, but with some gameplay ideas from Robotron added to mix things up a little bit, so I thought I'd make a more traditional asteroid shooter first to give me the base code for the new version of Retroids later. I'm not sure exactly how or if I'll release Asteroid Mining Company yet, but I'm thinking I'll bundle it together with Super Retroids as a freebie.
