I Have one small, and probably done to death idea, and a large idea that has probably not been stated before.
First up, make a Practice mode, where you can pick any level from any map and try to practice skips and whatnot. All melons could have a translucent appearance, to try and emphasise the fact they won’t give anything.
And the other idea: Make a timer mode. Basically, every level of every map has three times, A gold time, A silver time, and a bronze time. the amount of units you recieve depends on what time you get. Dying doesn’t reduce the amount of units you get, as dying almost guarantees not getting the best time possible.
The worth of melons could scale depending on what time you got, which would also add a way of making melons a thing that could be used in singleplayer. I personally think this is a good idea, but what do you guys think?
