Do we start the game with new levels or with old levels?
Your released version of BDS is no different from the one published in 2002 by Marcus Wagner. Even when it comes to level edits. To me, this is an attempt to cheat by signing off on other authors' games. The games you published are no different from the ones I already own were published much earlier.
There are just some bug fixes but the game was never published official. I gave it to a few people privately. You can ask these Marcus Schulz but the game was coded by myself. Also the first version Brektwon was coded by myself and distributed by Markt & Technik in the 90s. So there is no fake! Stop talking nonsens. If you like I can send you the source codes.
You coded both parts of Brektwon, but officially on various sites such as Lemon Commodore, Gamebase 64 the programmer of the game is Marcus? That's a bit strange. The way I understand it is that you wrote the code, someone then made a game out of it, unofficially released it, and you now want an official release, charging for it. And what improvements does your version have?
