Ok so I'm not sure about this, but I'm going to try anyway.
1. 50 million seems sensible. Sounds special and I got 25 mill before on other tables.
2. Sensible software haven't always been that serious, just look at the credits of cannon fodder. I'm going to guess on C
3. B? turkey is 3 strikes consecutive.
4. have no idea what game this is, but 100 levels sound like a darn lot. Guess it's level 1. Most games with 100 levels don't have a NICE outro.
5. I've tried different pacman versions without anything but a pain in the ass to have to get the power pills. I'm guessing a C.
