well, the original direction was putting it on an engine "not" in the rm family, but seeing ace and hearing very good things about it, the project might be transferred to that.
like, it really comes down to crucial factors, like the ability to code in 8 directional movement, rotation, and layers.
i'm still debating to release the prototype demo to people on rm2k3 or wait till the ace transfer so people can experience all of the features in the prototype, like fixed battle system, better platforming elements etc.
so, hopefully soon, in the near future. i'm bad with dates, so it's good to just keep following.
