2/5. Would have been 4/5, but some levels are broken in that you are forced to repeat them over and over again because you are completely reliant on luck instead of planning and strategy
Have the coins stay permanently or at least have an item for sale that permanently collects coins passively. Controls are pretty screwed up, there needs to be a way to quickly turn around when opponents try to surround you. There also needs to be an AWSD set up.
Re-balancing it already - the update will be here soon.
