Since my X-3 project is on halt since i use the free version. I made a small project Treasure runner.
I'll let the game do the talking for me. but here is a small desription.
"You as dragon, have the important task of protecting the treasure in the cave. It seems when you went to get a glass of water some knights snuck in to steal your treasure. Time to run back and defend it!"
IF you want to try out X-3 you can play it on my site or on clay.io
