Hi personion - I'm really sorry to hear that you weren't able to run the game :(
Thanks for mentioning your hardware specs and for taking some time to leave a response anyway - we're all overwhelmed with excitement at the responses and to refine things more.
It was a big, big mistake to not include some more options for graphics in the jam release!! I regret this one a lot - we're already working on improving performance, making some post-processing optional and other general optimizations now that the submission deadline has passed.
I think in the future it should be more than possible to run this game on a similar system as yours - and I hope you'll consider playing our game again once we've released some updates to address this issue.
