I feel like having only the regular Double or Nothing category, where you just complete 3 rounds and end the run then, is not what I had envisioned to be here. So I have a suggestion:

Separate categories that require players to reach certain cash amounts, like $250k, $500k, or even $1M, before ending a Double Or Nothing run. (On the black screen of course)

Maybe this will incentivize the usage of methods that increase the amount of cash earned per 3 rounds, while still incorporating certain time saving strategies.

Even if this doesn't happen, thank you for at least taking the time to read my suggestion.

Honestly, I know it's meant to be of course, speedruns, But I think it could be fun to just see how much cash people can get in Double Or Nothing, Obviously, doesn't fit have a time limit, But if you wanna make that to a speedrun category by itself, then just say, give people X amount of time to see how much money they can get, to really put glitchless players to the test.
