I like this game! It has a good bit of potential. Once I figured out I could shoot while rolling to gain speed, movement became a lot more fun.
The movement could be improved further if the armadillo leaned in the same direction as the surface they were on (for example they roll sideways when wall running (wall rolling?)).
Rolling up ramps also kills momentum. Not entirely sure how you would fix that, but it's something to look into.
Overall though, its a good game and I'd love to see more.
