Nice! That's pretty decent! Keep grinding away you'll level up in no time! The birthday cake is a super awesome card as well! Definitely worth getting!
Right now I can get max 1512 starbits per Illegal busking mission. (this is with a 19% ego!) I'm not too bothered about Ego at this point I just gonna grind out the missions =.
There are also 3 x5 minute missions I can do with similar rewards.
thanks for stopping by and feel free to bug me if you have any more questions!
