Can't play. Just see black screen after click start.

Hey great game! I played through it and here's what I thought as I played:

• The menu image is great, the text for the buttons is a little hard to see. Maybe lighten the text a little bit, or have the button that's highlighted a little lighter than the others. Small subtle animations like growing or shrinking would also bring it more alive!
• Your UI isn't scalable, so they stay the same size if the aspect ratio changes. This is only viewable if you leave the game in a small window, which normally players wouldn't do but it's still good to know.
• Atmosphere was perfect in the beginning, but when the music changed to a bit of a more up-tone it felt a little less atmospheric. Initially I was super freaked out because I saw the second character standing behind the wall that I had just opened, so thinking someone was in the room with me was HORRIFYING, but great! 
• A small bug I cam across, as I was trying to get through the second part after the 2nd computer (hopping down to the lower platform), I was swapping between the two players and it seems the red character was showing one position on one screen, but in a different spot on another. Maybe they aren't synced or if it was intentional I have no clue, but either way, i got stuck haha. 

Overall great game! I found this submission super unique and the screen portion way polished than I thought it would be going into it.
