Correct! Until recently, I had both the cartridge and the TI, but gave them to a friend of mine who collects old computers. Checked them, and they both are still in working order, ~30 years later...
I still have working C64 with this famous greenish monitor and I play some games on it from time to time :D
As for the game: I used to play it with my brother and once we reached 107 level (the only way to finish this game is... to die)
