Please update the app mr. developer

The game is very good bait since I’m not responsible enough my mom takes my phone away and so I can’t play the game and when I try to download the game on my watch it says “the developer need to update the app so it can be on your watch” so in conclusion if your finding apps for your Apple Watch it’s not threat good until the developer updates the app.

I love this game!

Honestly, boom it makes some great games. The fact that so many people are giving it poor reviews, just because they find it difficult, is saddening and unfair to the developers. Just because something is beyond your skill level, doesn't mean it's a bad game lol. Give it a try, it's fun and challenging!

This is honestly the best game I have ever played in a long time very exiting. I feel like with every level your first attempt is pure reaction skill and when that fails there is multiple ways to find a pattern and correct your errors to solve it. Completely recommend everyone to play!!!
