We're holding a contest at the official RM forums:
Summer Fun Contest
This is your chance to win a copy of Ace, or any other product that's currently on sale at the official store. The deadline is in 3 weeks, and all you have to do is create a summer-themed mini-game! So, if you've been itching to get your hands on Ace or if you even want to just have an extra copy of Ace to give to a friend, think about joining the contest.
