But it seems that in joiplay the models of the characters do not load and are invisible only from the wild lamia is the one that loads correctly the other characters do not generate their models, I do not know if it is only my problem
I suggested before I tried. The problem is that the phone (or rather its tools (I can’t name it exactly)) cannot use images that are too large (in terms of the number of pixels).
The only solution (for now) is for the developer to tailor the game to the mobile version by breaking the characters down into smaller chunks.
On earlier versions of android there were ways to simulate tools, but this only works on older versions of android, and the versions that supported this simulation have long been removed.
Yup, optimize the images could be the solution, but you could not expect much from an Android device. 
ngl i thought that joiplay could not run the game but surprise fence takes me, if the developer wanted to make a port of Android would only have to focus on those sprites everything else works, or if he can make a file optimized for joiplay, To avoid headaches in the port

The main thing is to find out the possible limit on the size of the image. Otherwise, usually the characters are divided into small scenes.
