Thanks! Yeah I was hoping to add more variety by expanding the map and adding events and such, but didn't have time to. The pizza spawn is technically randomized, but there are so few options I think it might not feel as random, especially when most of the houses need pizza after the first few runs.
I was also thinking it would be good to add more upgrades that are specific to combat too, since that would help give more variety and help out with the later runs getting more difficult after around run 10 to 15 with just the basic upgrades I currently have reaching their limit of usefulness.
