Hi there, just FYI I also ran into the same issue as Arrturion, even with the latest package. However I found and installed the runtime manually and it worked OK.
The game feels very polished, I think you really nailed the aesthetics. Unfortunately I wasn't able to get very far, I managed to beat the first ghost but couldn't get beyond the second enemy. Maybe the point was to die a lot (we are a ghost after all), but I think with a little difficulty balancing it could be a really nice little game :)
