Well... i want to show you some of my ideas...
-Will be fun have interactivity with stage, i dont know, how kill the oponent in some areas, or control some part of the stage for make appear some consecuences:
For example, imagine to Taffy and Bad mr. Frosty a fight in a secret base into of a volcano, make a recreation; Taffy can destroy some thing while Bad Mr. Frosty capture some object that help to him make a great combo, the scenary is more big now becuse the scenary was destroyed, but is more, he destroy the light switch, the light is some times dark becuse the lamp dont recibe the energy like must be. Taffy hit to Bad Mr. Frosty to another room, and they fall with a metalic platform for the lava, the lava that touch to bad mr. Frosty make him lose a little count of life. Bad mr. Frosty hit to Taffy with an iron stick, and make a combo, Bad Mr. Frosty finish him hit him from the lava abism. The metallic platform in some time finish in a new escape, for be near of Hougan's domains, or it finish in a beautifull beach.
Another ideas may be crash for a vehicle of the stage like finish move or destroy to the oponent hit him with the car over for demage him a little more.
-Return the old Hoppy Moveset: The old Hoppy have carrot granades and another types of attacks that T-Hoppy dont have.
-2vs2 players, like Tatsunoko vs capcom, where the players turn his time, life or in anycase his oportunity of fight. In this case 4 players can play the game turning his oportunity of fight.
-I love the insine combo: But like is very hard to make it, is better dont make the insine combo.
-Use 3 parody characters stereotypes from popular characters or people from the world: I love if you make a Ronald mc donald parody for Bonker, or a Terminator parody, or a Michael Jackson parody, i dont know, these are my form of think the character suggestions, but i think is much better than my ideas that you think what characters can been.
-Use another more stereotypes of interesting ideas: I recomend a Sentai character, but you can use interesting ideas, only need to enjoy seen it in the real world and fiction.
-in a future you can invite a clay console mascot fighter, like Mario and Link.
-For a little long future, Use electronic music or rock like daft punk or iron maiden type (with differents melodies but similar to the original songs).
-in the future update the game with ultra hypers (3 levels from power bar hyper)
-In a future, write the name of the claytality, for know almost what claytilities we are refering when we want to make it. In this case one person that search a claytility or ask of a claytility to a person, the claytility name can help you to identific the claytility... the claytility is not necesary, for that may be taked to interest in a long future.
