Demon's Regalia: Colosseum will have its next update soon. It will be small but at the least have one new character with it.

The Harpy will be added, some colosseum events, a fish for the fishing, and something pretty important: game controller support. The controller support isn't proper yet but you should be able to navigate 90% of the UI. I'll make it more conventional in a later update. 

I'm still working on the cutscene so I'll add it in later, like a v 0.1.7 b or something. I want to roll out the update with the steam sale so the cutscene won't make the first cut.
