It's an old game I used to play on the computer but I can't remember the name of it. Perhaps someone may recognize it.
I'll try to describe it as best I can.
It's an old 2d game where you play as a young kid. His dog is suddenly kidnapped by some nasty, dark creatures. In order to get it back he goes into his tree house which is full of super-advanced technical gadgets and even a ship! Unfortunately after fighting through some of the lesser creatures he stumbles upon some big ones who eat his gun and helmet. Oh and you also climb a skeleton of a dinosaur.
After that you eventually get to some lake where there's a big, green meteorite in the bottom left of the screen. Touching it gives you meteorpowers!
You can now shoot green plasma-thingys which can instantly grow an apple into a full tree.
You come across a race of weird skin coloured people with wings who you befriend.
Any help would be nice.
As I recall I really enjoyed the game back when I played it.
