Thank you for playing and commenting!
And thank you for the feedback :)
We are sadly aware that the particles lead to stutter for some and down right freezes for other players. We are planning to release a fixed version once we are allowed to. The crash for the black wall of hands was also addressed in a fix, but an unfortunate Git issue sadly overwrote the fix last minute, haha. So both of those will be fixed and the game will receive a general performance and gameplay overhaul! Thanks again for taking the time, Windfall! :)
