I FOUND A WAY TO BEAT LVL 2! ok just go slow down the hills, but, if you run out of room press right, your character should back up a bit, then get some speed and go over the gaps. Your character should get enough speed, but DONT GO TO FAST! thats gonna kill you. I got halfway through 3 but died cuz of the stupid lives system.
Also, I think there should be buildings. Like houses that act as a bunker on the field the same as a ditch acts like trench. You will see right through the roof but walls will tell you where doors and windows are. Maybe later on you could even add towns that have been bombed so there is scrap metal and rubble. This will add even more tactical thinking to the game, thus making it more fun. Please comment on what you think about this.
