First Question: How do you make a platform game? This has taken me forever to master and its still not right. I am working on a pack-man platform game where I got it, but I could't really say how I did it :lol
As for the life bars, I saw someone do lots of mini life bars, but I dunno how to do that. You can make a life bar by using the score tab and selecting the draw the life bar.
You can download my best and finished game, Bee Dodger,
Also you can download my unfinished game called Animal Games
And my other in progress game, Pacman Attack Since this one is still in testing and only has a few levels, you can press + to go to the next level.
EDIT: If you download them, please tell me what you think, especially whether or not I should continue the Animal Games and Pacman game.
