Thanks for the advice! I have Gimp installed, but when I see all those buttons I get scared and I've never really put the time to learn to use it properly. But you encouraged me hehehe.
And about the pop-ups, that was really never my intention to use them hahahaha but I had less than an hour to make all the mechanics development and I didn't had time to make some "normal" pop-up cute message interface, so it was the fastest thing I imagined hahahaha. But I think it could be an interesting idea, to put it in a game and make it more like an immersion thing.
Thanks for the feedback!
