yeah my bad, you need to press X to buy things from the store and the amount of money you get increases with the round number. The first few rounds up to round 5 are like complete rng on my part, but its basically a free win after that because you can get the x2 multiplier. I'll probably keep working on this game because I've had a lot of fun making it, but it's not really up to a state where I can say I'm super proud of it yet. Thanks for the feedback!
