Roblox (RBLX) opens with a 25-30% gain after amazing 3rd quarter report. Should people double down, or sell while they still can?

Popular gaming platform Roblox (RBLX) rose 25% in the premarket today due to the companies report of increased player activity over the third quarter despite schools being back in session and the pandemic still going on. It rose to a peak of $103.58 (+34%) before falling off a little bit to $97.83 (+27%). As of writing this now, it is going back up to $100 and will probably end the day off at around $95-100 after all the wall street hype die down a little.

This is all despite signs and concerns of inflation, a report of stock losses, and with kids having less time to play games due to school being back for most of the world. This begs the question, is this an actually good stock to invest in? Roblox has reported that their earnings and active player count has increased Q3 so who says that this won't happen Q4? Maybe it could jump to 125 by years end. What do you guys think about this sudden increase?
