They gross me out. Both visually and hearing the buzz sound. Ugh, shivers. Oh and screenshots come out completely white. Like a sheet of paper, just plain white.

I'm having two high-DPI monitors (150% font scaling, in case this matters). The game starts in windowed mode on monitor #1. I drag it to monitor #2 and play a level. At the end of a level, when the next level starts, the game window automatically jumps back to monitor #1. I have to drag it again to monitor #2. This is annoying, maybe the application can remember the screen it is onto and not move itself onto other screens automatically....

... At least for french version.
