For Patreon? No not yet, its still under heavy work and testing. Plus they also trying to fix the bugs they had for the arcade mode crashing.
Im not sure if Itch will get the Arcade mode version of the 2.0 when the Night 2 arrive for Patreon, but once Night 2 arrive on Patreon, Itch will likely get the updated content of the Arcade mode, and likely so in a better state then it is right now for Patreon. This is what happens when people cant wait for the next update. It gets horrible bugs that isnt fixed yet because they have to rush a update.
The update was split in two, because of the delays, and people keep complaining over not getting a update. So right now Patreon only have the first half of the update, and thats the Arcade mode.
The other half will be the Night 2.
