Hmm, you should be able to type when it asks you to enter a number. If you click away it might stop taking inputs, so try clicking on the black bar at the bottom or refreshing the tab. If that doesn't work, maybe the 100-sided dice is on break?
Yep! I actually just came back to it and it worked this time. No clue what the problem was previously, likely something on my end. Although now I'm lost on what my goal is. Cause I definitely picked 100 and it said it rolled a 99.9 (I win, right?). But you say it's beatable, so I'm determined!
