Hi!
We don't have concrete system requirements, but it should run on any newish computer: Have you tried deactivating the option "Post FX" in the settings? Usually that's the most performance hungry graphic setting!
If that still doesn't help, please let us know and send us your machine's spec, so we can take a closer look into it!
For future versions we hope to improve performance (which, admittedly, was no priority during the game jam, haha) and offer more detailed graphic settings!
