I like the general concept and was able to win pretty quickly!
I think the upgrades aren't really the best, it mostly boils down to just 'get more money (which is perfectly fine of an upgrade)' and 'win easier (which is where I start having problems)'. I think there could've been room for strategy here. Maybe an upgrade that gives you more leniency, allowing for a wrong roll or two without breaking your streak? Maybe one that would count inconclusive rolls as the next number in the sequence? I feel there's a lot of room for strategy that could've been explored. The extra dice was a good step in this direction, but given how expensive it is compared to the other upgrades, going for it didn't really cross my mind at all.
TL;DR: I think more varied upgrades would've been good.
Even still, pretty solid submission! Art looked nice and the sound design was really good. Good work!
