Скидка на The Twin Paradox. Support the Developer DLC

The objective of this game is to teach and promote science. That's why I felt it was right for it to be free. However, if you really enjoyed it and would like to help me finance future games, you can purchase this DLC as a show of support. In return, you'll receive a small cellphone wallpaper as a token of my appreciation. You can find it in the game's installation folder. Thank you for trying out my game and visiting this DLC page. Let science continue!
