I think that of my movesets for Food Fight so far:
M&Ms > Ronald > Chester
I feel Ronald's potential was squandered a little by my aim for a shoto archetype (though I don't regret that decision either, necessary evil) while I wasn't really paying good attention to Chester's archetypes (he's a stance fighter) while making the moveset and didn't lean hard enough into the extreme sports Poochie angle. Red and Yellow on the other hand, I feel everything clicked for - a decent reference/hammerspace-to-regular-attack ratio, a well thought out gimmick that was considered for all moves, a good grasp of the duo's personalities, so on. It's funny too, because the concept for Red & Yellow's gameplay was something I've considered before in the context of multiple characters in multiple games - hypothetical and real - but always dismissed, however once I started thinking about how Red and Yellow could be implimented the climber + slapstick concept kinda clicked for me.
