I have recently started playing with a tool called GameMaker Studio. As I am working through the tutorials, I will endeavour to put some of the examples up here.
The first one is a 1945 type game. This is pretty much exactly as it appears when you finish the tutorial so I can’t take any credit for the design of it.
Simply unzip the file and run the .exe which is an installer for the game.
And here is the latest tutorial I have worked through, it is just an exercise in particle physics and using the tools available within GameMaker Studio:
And again, it is an easy unzip and install. Play with it, then probably delete it, but it does show some cute effects available within the tool.
