I have been making levels for around 3 years now and still can´t figure about few things.

1. What is this laser shield, when I try to use it, it isn´t there but I can push it and walk on it e.t.c. I can get it with cheats but it would be nice if you can put it into the game.

2. Some kind of shoes with wings in the goodies, I can´t see what they do.

3. A boss that dissapears when used. I don´t remember the name.

4. At last, the TNT powerup, it works like the laser shield.

Please tell me what those items are for.

Thanks.
