I've been working on the rainbow tower- mainly the arcade zone and making minigames. The other thing i've been doing is expanding the refining system. you should be able to get every TM via refining in v0.5
I've been making some storyline refinements.
been mapping out rainbow tower. finished 1 minigame for the arcade zone.
Street Combat. 1v1 fighting game. get points to get rainbow credits that you can trade in the prize zone.
I've also made a "Street Combat: Overdrive" which is just a double speed version.
I'm planning to make
Street Combat 2
-better graphics, storyline.
Street Combat 3
-better graphics, multiple rounds
Wack A Mole (diglett?)
Random "Light Gun" shooter
