I actually have been working on this.
It's super rough right now, but imagine that without any bugs and you'll get an idea what I'm talking about.
Known problems:
a) You can't play it big because the smashing attack will instantly kill you due to sending you into the ground. They do the same when you are small, but you expect to instantly die when you are small.
b) Random number generator crap causing it to be difficult to hit him sometimes. I'm planning on implementing a weighted system that will increase the probability of getting an attack the more times in a row it is not done, but that's not done yet.
c) The intro looks weird and you can move during it. I don't really know what would be good in that space, so ideas would be great.
d) Sometimes when you get smashed by the fist and there is another fist nearby, you'll get a brk. Don't know why, but I'll work it out.
e) No sound or effect when you jump on the helmet, and also the helmet doesn't crack at all. Adding those later, and waiting on the cracked helmet GFX.
f) Obviously norveg isn't going to be just sitting in there with his jetpack, I just need graphics for him pulling levers and such.
g) Second time entering the level, the graphics go nuts for a second or so. Some uninitialized ram or something, I'll work it out.
This is just the first phase, but it's actually a good portion of the way complete, so there it is.
