Unfortunately, (hey, someone else used that word too) the game isn't playable in this state. Having to relaunch the game each time I die is unacceptable, given that I die a lot because I suck. It might sound a bit rude, but you need to focus more on details like playability before writing a convoluted story about evil scientists and an army of robots chasing you to death.
Don't give up ! Take time to test your game next time and I'm sure you'll be able to make something great !
