I made my first commercially published game open source and released an installer to this platform. You can access the code on GitHub. Unfortunately the product was only distributed in German speaking countries and so the game is only available in that language. But do not hesitate to translate it, if you want to.
Objective of the game, which takes place in the future, is to trade materials and goods and to earn profits, so you accumulate the money to purchase a space ship and escape an assassin. He is hired to eliminate you and collect the debts, you owe to a syndicate. While traveling from place to place you have to evade him.
