yeah, the game rate is frame rate independent (unless of course you are playing on a legit potato and get super low frame rate of course, then the game slows down for obvious reasons)
Depending on device the browser version can go from same as exe to waay harder than the exe. I added the rules to the description of the game in case you are curious what the rules are.
But thank you so much for taking the time to answer, will think about more visual cues <3
