Brillaint
Perhaps the bast game to be released this year. It's amazing. The difficulty is just right. However, I found some glitches to help you win.
For the first challenge continuously jump.
Second Challenge, run to the far right of the screen, from there you can't be hit.
Third one is a little tricky. It is actually easier to stand in one spot and move just to the left or right.
The boss level, however, is a tough one and requires practice.
The game is brilliant though and creative and great fun to play. I won with 6 lives remaining so it is possible.
All I can suggest is a scoring table perhaps. Or have collectibles that can be picked up. Also more levels with some better music. With these impovments you have your self a winner game.
