Hey! Thanks for playing and what a wonderful game you have submitted yourself :)
Yes there is a voluntary delay after each click, it is meant to be. The idea behind it was to create a bit of suspense after each click instead of having instant knowledge if you were right or wrong. To hold the player in the unknown for a tad bit longer. That's why the delay is so long :P
However I didn't have the time to implement visual feedback (a loading cursor maybe) and prevent additional clicking / accidental double clicks, so I understand it can be offputting!
I'm curious to see if more work will make this feature better or if I have to drop it out.
Thanks for this precise feedback!
