I’ve been waiting for confirmation in the superhot VR game for 5 days, is this a long time?

No. The standard grace period is 21 days. Usually 1-2 weeks is roughly how long people take, but its entirely dependent on the moderator.

Having said that I'll ping the mods for you, they are definitely active, just getting closer to end of year they are probably busy with family/school work or whatever.

thanks!
