I just downloaded the source, copied the executable into the same folder and then it worked.
Ok, so, I know my game kinda misses the theme, and so does your. Apart from that, congrats for your courage in using C++, I've made a game in it many years ago and I know there's a lot to learn before you can do even before showing any graphics on screen. The graphics are very cool. I think the character is sinking into the floor each time they land, is it a bug or is it meant to increase the challenge?
