A few comments on the editor - In working on my level I accidentally put a peanut someplace that I didnt want - I dont see a way to remove peanuts?
Also I drew a grider which I removed using the erase tool. I tried to create a down rope where I erased the girder and it wouldnt allow me to draw where I had "erased"
Is there an easy way to pick a new "bullet" shape or do you have to write code?
The way to remove something is to select it using the arrow tool (it will turn light blue), then use Cut (Ctrl-X) or press the Delete key. I'll have to add a Delete option in the menu.
I know I don't have a user's manual so I apologize for the confusion, but those erase icons are designed to be used in the trigger painting, not on the main level. The three things, Erase Girders, Erase Ladders, Erase Ropes are drawable objects, the only difference is they draw background colored pixels. I'll have to change the toolbar so they aren't available when drawing the main level.
And the effect you saw, not being able to draw where you had erased, is because Jumpman sorts the objects so that erasable objects always appear on top of drawn objects.
About bullets: there's a way to make them bigger (ala Jumping Blocks), but not change their shape. They are the missiles, so they are only two bits wide. So, yeah, if you wanted different shapes you'd have to do some custom code and use a player object, or use multiple missiles or something.
And BTW: your level is challenging! I still haven't completed it.
