I'm honestly starting to lose track of all these people so quick to jump on the gamedev train. ('-' )
If you want to work with ActionScript, I'm probably one of the go-to guys for it on this forum. You'll want to start
here, which will probably point you to
here to download a free development environment for editing AS3. It's Windows only, though. If you want to develop AS3 stuff on Linux, you have some hoops to jump through. Mac.... all I can say is "good luck".
Though I should mention that if you're planning to release on Android, you might be better off going with an HTML5 library, such as
phaser.io. Haven't tried it yet, but
/r/gamedev on reddit says it's similar to
http://flixel.org/, which I had used before flashpunk.
Melon JS has quite a nicely done starting tutorial for a basic platformer. The reason I suggest these is because Adobe AIR, pretty much the only way to make Flash apps for Android, runs abhorrently slow (at least on my Xperia Ion). But then again, who plays hentai games on mobile platforms? I sure don't. Anyway, I know just enough Javascript to write cute little bookmarklets that describe random bimbo transformations and a page that calculates results of fusing weapons in "Kid Icarus: Uprising", but it probably won't be too hard for me to get the hang of things.
Inspiration, however, is another story. I have numerous text files with SHIT TONS of random bimbo game ideas/shenanigans, but it's been rather difficult coming up with a satisfactory game design that incorporates a good balance of fappability and interesting gameplay. I'm probably aiming too high (Think: Gunner-L/Milktank quality. His latest release,
"Mighty My Master" is so good it's fun even without the hentai)
I'm leaning towards 1: Megaman-style platformer. With a top-down zelda, AIs are easier to program, but there's a lot of spritework to be saved by opting for platformer, especially if you're considering expansions/clothing ripping In fact, might I suggest using
this as a base and applying whatever appropriate curves to make it more "feminine"?
Finally, one last thing. Regarding the "crazy shit" level, are you sure about that? It's generally best to work on aspects of a game you know you'll love and leave weird things (such as udders. Didn't you dislike udders?) to the modders.
