Bolt Bolder!
It's very easy to play:
> Watch out for the screws coming from above and tap the screw box of the correct color
> Sort the screw boxes correctly
> The screws will fit into the screw boxes based on their color and size. The goal is to perfectly complete the screw boxes
> Watch out for surprise screws and screw boxes
> You can use boosters to make things easier on the more challenging levels
Enjoy Bolt Bolder!
