Thank you so much as well, I am so happy that you liked my little demo GB studio game. I used 3.03 to make it, I sent the source code to your email. Also in regards to what you said about making it work on Gameboy, I completely agree, it is a very complex game for the C64 but reducing the movement, and the complexity to make it work on Gameboy, I think the game would still shine and be fun! I think the ZX Spectrum version managed to simplify things in a clever way. I based my graphics off of the C64 version, but the ZX Spectrum version has even more simple graphics but they still look very nice to me personally.
