You know, stickmen is a very interesting and useful element. It allows users to create uploads, like games or fighting grounds, that are impossible to make with only other elements. But there is very few creations like that: no one wants to use stickmen. Why? In my opinion: stickmen have some major problems:
1. You have to keep mouse on it to see hitpoints. It's pretty hard to both keep it moving and watch it' health. Also, you can't see hitpoints of both stickmen at the same time. Suggestion: hitpoints should be displayed constantly, over it's head or in the corner of screen.
2. It's hard to see if the stickmen is taking damage. You have to check hitpoints to know that. They should twitch a little or jumpto represent their pain.
3. Stickmen are very fast. This makes them hard to control. They often fall off edges or jump over holes in the ground. I think that should be much slower. (about two times should be enough)
4. Stickmen are bad jumpers. They usually jump from 2 to 5 pixels vertically. It would be useful if they could jump higher.
5. They can barely climb up slopes and ladders because they always fall down. The friction should be increased to allow stickmen move or stand still on these obstacles.
6. They can jump through particles. It's pretty hard to keep it in a building: the first jump may launch stickman to the roof. They should be blocked by solid particles, so that they can bump into a wall, but cannot pass through it.

These changes would encourage players to create great works with STKM. There is much to create: castle sieges, prison escapes, arcade games and torture chambers.

Have anyone got any other other ideas?
