Amazing, but make sure you use WiFi

This game is perfectly paradoxical for its simplicity is what makes it entertaining. This game takes a different spin to puzzlers out there, and I can’t say that I know any other game like it. However, there appears to be a bug that hinders our fun. If you plan to take this game on the road, I hope you have a portable WiFi router because it cannot function without WiFi, not even Cellular Data can suffice as a replacement. May you please, the developers of this game, find the issue and eradicate it so this delicacy may not be tarnished.

Hi MrSkinnyFingers. We had some server issues yesterday which should be improved today. Please let us know if you have any more issues. Thanks.

Overall very solid.

Solid concept, simple and yet novel in its approach. Puzzles are fun, this ads done right—they’re present because they’ve gotta be, and they really aren’t egregious. Took off a star for some of the styles of the puzzles. There are a couple that, to achieve perfect on, you’ve got to make several jumps with a terribly small margin of error. I dont need speedrun practice training built into my puzzle games. The strategy of figuring out fastest route for time, as well optimal jumps, is solid enough.

Best game ever!

This game is so fun and entertaining. It is difficult at times, but not so difficult that you can’t play. It also includes a feature where you can create your own level and play other peoples levels. My only problem is that there are adds, but not to many. I like how you can get 200 bits just by watching one add. Thank you for creating this awesome game!
