i played and think you must be extremely careful flying as getting closer to enemies but since the red areas are insnat death you are likely nudgeing death each time on either level 6 and up when enemies are so close and you must make the timing to precision perfection or you are bye bye 1 life short for each slightly touch of misstake. i think maybe extra life for each 10000 instead of 20000 can be a good option and unlimited dynamites
