how do you buy stuff?

got not that far in bonus rounds, wave 23 and then my game crashed :0

Had to close it through task manager, all I have to say is- "Hello :)


i played a 6* hour run and forgot to pause and died.



Hey, love the art style and action-oriented gameplay. One question: how do you obtain currency? Wasn't able to purchase anything from the shops


Currency is the little fellas dropped by enemies sometimes, this should be stated in the help but it might not be super clear.

(1 edit)

Are they displayed on your screen as the number next to the crosshair icon? I was confused because in the shop it shows dollar signs

EDIT: Yes they are, figured it out

good game!!
