Thanks. I'm actually working on a tutorial. In the beginning you can see the villain of the game teaching you how to move and jump. But that's all I got so far, after that he shows you how to do all the other stuff.
There is music... ? I mean, I just tried it out and there are indeed music and sound effects. There's probably something wrong with your sound mixer?
I'll add that soon.
The blowhole on it's head is there so it can breathe on land, while the gills are there for underwater breathing. It's all very complex, trust me (totally didn't just come up with that).
How do you do that with Game Maker Studio?
