Thanks for these advices.
I had to choose between a nice amount of animations but very few characters, or a lot of different characters but very little animation. That is why only their picture is displayed, but the pictures wriggle, a boot or a fist crosses the screen, or there are animations a bit like in Earthbound. I wish I could but I just can't create fight animations for 130+ different characters, so I had to find another way to animate the battles. Also, when playing Earthbound or Harry Potter RPGs I found boring and annoying to have to navigate menus to choose an attack every time, so I chose a quite random but more simple, direct and touchscreen friendly way to fight.
There is a story. You are a ten years old kid, it's summer and most your friends went, but it's your birthday and you got two pocket-wrestlers, so you go outside and start to fight and collect them, trade them for money, buy stuff etc. You come across a kid who has lost her kitty cat so you start searching for it. You learn that the kitty cat was seen near the the door at the West of the village, but that door is stuck and maybe someone could open it with a big kick. They tell you to go to the pub at the East, but you have to find a way to look older because kids are not allowed inside. And so on. You later have to find how to enter the castle, help the king, go to the island, find the champion, find a password to enter the cave, find how to defeat a giant spider, etc. In the menu, a "I am lost" button tells you what you should do next.
Yes there are a few female wrestlers too, and by the way you can choose between a male or female kid to play.
The game can be played directly in the browser, no need to install it, so check it.
