Thanks to the reports of some nice people, I was able to improve the version a bit and fix some things:

 
- mouse smoothing auto disables at low framerates (like before, you can also turn it off completely in the menu)

- there was a bug in the symbol wall that added 5 more symbols every time you changed the difficulty :D

- there was a bug when restarting the game and selecting "continue" that would prevent you from interacting until you opened and closed the menu once again. This was caused by a recent hotfix, so that version didn't exist for long enough for it to get noticed.

Thanks for reporting, everyone!
