one key problem
This is a great and creative game, however its too easy to break the combo to push the rock back. This is essential to keep the game going, and its just a bit too hard, specifically for one reason.
The gems on the far left and far right are the hardest to reach. Presumably players stay in the middle, so they have a shot at getting gems from either side to keep the combo going, However because of the shape of the screen for perspective's sake, the gems on the sides are seen for less time than those in the middle, and appear 3/4 to the bottom rather than at the bottom, then players must make a split dash and hope to get them, but there usually isnt enough time. The side gems are just too hard to get, but that wouldnt be such a problem if missing one didnt wreck your entire combo.
For that I have to give a lower rating, sorry. Other than that it is a good game
