We are aware of an issue in which players are experiencing slow and sluggish in-game movements while playing Word Whomp HD on the Microsoft Edge browser. The team is working to fix this issue.
We recommend playing Word Whomp HD using the Google Chrome or Mozilla Firefox browsers at this time.
Also if you all do not this you can type the letters using the keyboard and hitting the enter key to submit words. I have found this to make it go by faster. Just a suggestion.
Good tip, thanks, LF
