Suggestion: Show each others current ...
It would be great if we could see how much cash each other has to spend during gameplay, that way we can better share coin drops between us. It would make it easier to ensure that we both have enough to create the kill boxes we desire.
Money transfers? Why? I thought part of the challenge was dividing the traps accordingly so the balance stayed even between players.
True. I guess it's less of an issue doing regular maps because restarting is fairly quick, but on endless it can be a real pain. Especially when you realize after 1h that one person accumulated 10k while the other struggles to have any money. It's not always a matter of trap cost as much as the number of each you'll be using. Unless you've played the map before and have a strategy already prepared, it can really hurt, even when using coins to re-balance.
I don't understand why the coin you pick up isn't shared like the kill rewards are period.
If they want to keep the HUD minimal then have it show only during the break periods. Maybe a different colour under your own cash?
I would go one step further and allow money transfers on go breaks.
