You tap space or click anywhere to deflect, it’s a timed interaction where two circles overlap and you have to interact right when they overlap. You can do it from the start. It sounds like this part wasn’t blind friendly though, but I’m glad the spirit deflection worked.
In the alpha, after you defeat Gemma and the Inquisitor and see the throne realm, that’s pretty much everything.
The outfits are classed based on how revealing they are (normal, sexy, and lewd) but this doesn’t do anything for now, they’re purely cosmetic. The knight and inquisitor outfits are for your throne realm attendant. I believe they’re marked as such, but a lot of people make this mistake, so I may in the future split this off into a separate shop screen.
