Hi! Are you using the Mac or Windows build?
When you say you couldn't get it to work, did you mean the game wouldn't launch, or the controls didn't work?
I'm running on a Mac. I used the itch.io desktop application to install and launch this game. The game launches and runs and I can see the title screen, then the pre-game cutscene, but after that I just see a static image.
Here is what I see: http://imgur.com/a/isqb2 (The third screen is the place I'm stuck)
What operating system are you running on? Have you tried different resolutions or running it with a lower graphics quality?
OS X 10.11.4, MacBook Pro (Retina, 15-inch, Late 2013).
I thought I tried different resolutions and graphics qualities, but apparently not, because it seems to work when I change both. I'm playing the game in windowed mode, also. The game appears to not function at 1024x768 with fantastic graphics, but seems to work with 800x600 with simple graphics. At least I can play it now. Thanks! Maybe some of these details can lead to a patch if you're up for it.
Glad to hear you got it working! Sorry the resolution and graphics quality messed things up. I'm running my build on an OS X 10.11.3, MacBook Pro (13-inch, Mid-2012), so yours should definitely be strong enough to handle it.
