the lives system is terrible... i would have prefered a select level system and infinite lives because lives in this game means you are penalized even tho u have already completed the level make a mistake and when you make it to the level you are trying to solve you have only 1 life remaining even tho u could solve the earlyier levels. also i wish the aiming anamolys system was more accurate especially since it requires precise aim (my spelling sux)
