I've been hooked to this game since I started playing it a few weeks ago. All the elements of the game require some logic or memory, which I love. It gets increasingly difficult, which keeps it challenging. There's a pretty interesting storyline, which slowly reveals parts of the mystery of the town (and how your character got there). I do find the paid options way too expensive, but thankfully it's very doable to play this game for free. The amulets are brilliant and keep me playing for hours!

Please remove the misclick penalty on Pairs. On higher levels the items are so small that you can easily hit the wrong one by accident and it punishes you. You can't even win Pairs with random tapping, so why punish it. With tapping on a phone screen, you can't get such a level of precision as you would on a big screen and with a mouse. Also, waaay too many tournaments and events. Two tourneys a week, plus a new event every other day is overkill! A 5 day tournament per month would be better.

I used to really like pairs room, but the penalty for misclicks triggers way too easily now. I'm playing on a tiny phone and sometimes the visible area is very small, even zoomed in. Even deselecting the wrong thing you selected by mistake counts as a misclick. It's gotten so frustrating and ruined the minigame.
