For now, the only adversity is the time limit, although I didn't even manage to design a proper level, this is just the prototype with working mechanics :P
I plan on adding some new things to at least have it playable up to a few levels.
I had other mechanics in mind, like the player could switch colors, and only connect to balls sharing the same color. But well... that's it in Game Jams, sacrifices have to be made ;P Still happy I managed to this, being my first puzzle game... learned lots!! :D
Thanks for your comment!
