Are you ForeignGuyMike
He made that game for java 2d video tutorials on youtube.
If you are, I need to thank you. I learn a lot from that channel.
If not, well.. All the stuff he made is free, I think. And he never finish the game. I wish you luck to finish it.
Also, one tip. Tutorial 8 he made for sound, don't work on Linux. And attack system in my computer is bugged. if you press R and W (I think) he spam all possible fireballs. Its good for a combo.
