Hi, thanks a lot for trying the game! Sorry about the technical issues.
I've now posted an update that speeds up the text if you hold Space, on top of making it slightly faster by default.
I haven't been able to reproduce any crashes, so I couldn't fix that, sorry. If you try the game again and it happens again, please let me know what it was doing when it happened. (Also, make sure to click on the game so it's actually focused and getting keyboard input.)
