I'm just beginning to use FlashDevelop and as3 in general. For my first project, I'm trying to make a simple platformer game. I'm using the flixel engineto create it. I've done some basic concepts and gameplay for it, but i'd like to get any feedback or ideas I can to make it fun. Any ideas at all would be good.

move left and right with the arrow keys or a/d.
jump/double jump with the space bar.
The up arrow or w sets your spawining point (a red circle).
For every five blocks that disappear, you get one tile in your inventory.
The down key or s sets a block down directly underneath you. You can set up to 3 blocks.
Falling off the edge lowers health.

Sorry that it's not even close to being done. I was thinking that with the inventory tiles you could "buy" upgrades or something similar. What do you think?

Here's the link. http://games.crazygamezone.com/games/platformer.html.

Strong start, keep iterating.
I didn't understand that there was unique mechanic until I finished playing; came back here and started writing this:
So play with the level design and see if you can find a layout that exploits the fun in your mechanic. (If not, change the mechanic.)

Good luck.

Thanks for the input. I'll tinker with it a little and see how it goes.
