Really nice game! but I agree with rodoherty1. I would prefer some kind of checkpoint system so that you don't start from the beginning all the time.
Hi, if you are playing using a C64 emulator then you can save your progress using the snapshot feature - and if you are playing on a C64mini then that allows you to save your progress whenever you like :D
I use a real C64
You could use a freeze cartridge like the Action Replay to save your progress - that would work on a real C64
There is a cheat mode for infinite health if you wish to know it.
