I was thinking about simple application I can develop in few hours, but that matches theme of hackathon. So I came up with idea for educational game.
What it does
How I built it
What I learned
What's next for Play and Stay
Application can be developed to have several level, each explaining what are pros of staying in EU at different fields. Also more informations can be added. Moreover more enemies, guns and better mechanic can be implemented in game.
