Just Right
I'd say that no more work needs to be put into this game, it's very frustrating though. You'll work your way up and almost win and then get bombed by 3 or so 0s or 1s and then you're all the way back to the middle again. I was able to play for about 5 minutes without winning or losing so I'd say the varibles are perfect. It's addicting but also makes me want to pop a vein at the same time. I wouldn't say this is a good thing. Next time aim for a more user friendly game where you can get upgrades or something, something to keep the player happy.
