Hey there! Sorry this happened. I'll try and figure out why it failed to run properly. Can you please post a screenshot of the black screen (window mode)?
A few questions. 1) You're running on Windows, right? 2) Could you possibly delete the game folder, and download it again?
I see. Hmm, I haven't encountered this exact problem before (I have seen a gray screen which means a room scene fails to load).
I'll try and fix it this / next week.
Care to add me on Discord? I'd like to send you a test build when I have one ready, see that it solves the problem on your end before I upload it to Itch. On Discord I'm: Cosmic Void#8841
If you don't use Discord, please send me a DM on Twitter. On Twitter I'm: https://twitter.com/Cosmic_Void_
As soon as I have a test build ready I'll send it over!
