It was kind of like Elona but you could pick different characters who were seemingly from other media and had all different game play and traits. There were a few different dungeons you could unlock and each had different themes like tentacle/oviposition, petrification, etc you would be able to unlock. Progress was not tied to the characters and when one was defeated you could go rescue her with another. The characters seemed to be added and maintained by different people like open source. It was roguelite and had pixel graphics with character portraits that would change as things happened to them.
