I did some tinkering around with gamemaker and finally found a way to export the exe. file. This will also send all the needed materials for the game along with the file and thank you so much for your help :)
Hm, this doesn't quite work for me.
As I understand it, you exported an exe, that is supposed to read in the gamemaker file. This sadly didn't work for me :/
Maybe you can create a setup exe? The other MiniLD entry that is submitted so far was also made in Gamemaker. SuperMC123 included a setup exe and it worked fine.
