I believe Construct2 should have some additional native functions:
1) Explosion for physics
2) Climb ladders for platform
3) Layout transitions
4) Export to Flash ( HTML 5 is cool but there are thousands of sites that only accept games in Flash )
5) Pause the game when the user clicks outside the layout
6) A better way to pause the game, events and behaviors
7) Easy way to copy sub-events in the event sheet
* If I remember something I will add to the list.
PLEASE leave your comments with features you'd like to see in Construct2.
