You know, if there is a wisp, there will be a fire. But I can find only 2 of the wisps. One is in Intersection (4-5), the other one is in Mirriored Precipice (Mirrored 2-2). Let's talk about them. :)

When exiting 'The Bridge'; I'm getting a popup message to install Tumblestone. I know you want to make money off of your other games, but don't force them upon your customers. In 'The Bridge' game or store; post information about your other games. Don't ask me to install something I don't have any information about. I will not be referring 'The Bridge' to others; as I have in the past, because of this horrible process....

Great game I have really enjoyed it. I am on the last puzzle of chapter 4 which makes me sad since I only spent 2 hours so far getting here. However I hope there is a bit more and still achivements to collect. I would love to see some DLC with some new puzzles. Either way great job!...

when I click start the game, it shows nothing, after a while, the button become start the game again

I have a 2560 x 1440 monitor, and it seems the game is running at a lower resolution and scaling up to my resolution. Sorry, I kind of like to play games at the native resolution, not 1080p or 720p scaled up like the game is doing.
