The character flashes did sort of glitch the surroundings, and it turns pixelated for like a second..But it only occurred few times :>
Thank you for letting us know, we also noticed this upon creating the web browser version of the game.
Unfortunately, there's nothing we can do as the downloaded version of the game doesn't have this issue so the coder is unsure how to fix it.
We believe that it's some form of buffering as it only occurs when the game first loads certain assets. If we do however discover that this is something we can repair we will definitely patch this.
Thanks again!
