Thanks for the reply! When you say "Keep in mind, the template supports PC only currently, but you can modify the events to support touch as well". Does that mean that currently it won't work on an iPhone or Android because you need to enable "touch" to be able to swap the pieces?
Sure, you only need to play with the candy swap events, to make it support touch as well, currently its Mouse only.
GDevelop is the same on all platforms, so if you have gdevelop, then you can open any .json file which is the project.
Just make sure you unzip the folder you downloaded using WinRAR or any unzip software, and then you will get the .json file to open in gdevelop.
