Yeah: if you can make a game in Java from scratch (including, I'm assuming, drawing functions), I have no doubt you'd know how to write Android & iOS apps. ^^; Which also means your skills are valued, so no pressure; get what you need done first!
Yep! Draw functions too, I would have written sfx too, but I really ran out of time. Yeah, I hope I can do this one in about 1 - 2 months, but we'll see.
