Thanks for playing the game and for the feedback! By timer, are you referring to when the rat swarm appears... tbh I'm not sure how much I like the swarm, towards the end of the jam I started getting other ideas for risk mechanics but didn't have enough time to implement them. The coins were mostly just a hi-score mechanic, but I definitely could've made that more clear. If I keep working on the game after the jam, I'll definitely add more uses for them =) also, I love your profile pic
