I have watched the video, and it is normal there. BetHog team has designed the game in that way. The game is playable, but you will fail to cashout on a desired multiplier if you try to do it manually.
Did you experience that yourself (unresponsive
cashout button)?
If you are unable to manually to cashout at the desired multiplier then this is
definitely a serious issue that needs to be fixed asap as it may cause losses for players
while they were supposed to win.
However, I guess the issue is only
withrelated to the animation which doesn’t affect the game's functionality
but still needs to be improved (it doesn’t look that good/attractive, tbh).
