This is very nice  

nice idea

It was modified, yes, but afterwards I realized that my earliest version (which had light blue highlights on the dirt tiles) worked as well, for the same reason you said. Color 1 - orange, color 2 - l. blue, bg - black. 

hm. has the mockup been modified? what i see here seems plausible with bg black, color 1 orange, color 2 light blue. using color splits the colors for the score and life sprites should be no problem either.

Alright, thanks.

Sprites and characters are different. On sprites you can use any colour as the free one, not just 0-7.

Also the light blue needs to be in the global colours if you want a light blue sky, because light blue is not in 0-7.

Edit: Oh yeah, I think your current version would work with orange, black and light blue as the globals.

Sprites would be problematic, unless you make the crows beak light red. Then white and light red could be globals for the sprites. Jim would still need quite a lot of sprites either way.

So every 'char,' regardless of whether it is the player sprite, or a platform tile, or a background tile, can only have the background color, 2 colors of choice, and 1 picked from 0-7? 

In other words, if I took out the lighter blue from the main platform tiles, and, say, replaced it with the purple, I could keep the dark yellow-brown color? 

Edit - realized that the 2 colors of choice are global throughout all tiles, so the only way to fix it is to change the yellow to one from 0-7. Is that right?

Scratch that, I think I've got it - the problem is that the light blue and dark blue are the 2 global colors, so the yellow must be replaced with one from 0-7. However, since the light blue is not needed as a global anywhere else, the easiest solution would be to use the yellow as the 2nd global (with the dark blue), and to change the light blue on dirt tiles to an 0-7 color. That way, the yellow isn't ever used as a global, but it can still count as one. 

Edit - this now creates a conflict with the colors used on the character sprite. Too lazy to fix all this, gonna keep it mind for the next one. 

Check this out. That should help.

Hm. I thought that each tile could have 3 colors + global color, which was black.. Are static tiles restricted to the first 8 colors, where one of the four from those must be the global color? 

Also, I don't understand what you mean by "fixed color," as well as how I can have more than one global color.

Pretty cool. Would probably be doable, more or less. But using the orange (browny colour you got on the ground) as a non fixed colour is not possible. It looks like black, and the 2 blues are your global colours. You can only use the first 8 colours in the palette for the 4th tile colour (black, white, dark red, cyan, dark, blue, dark green, yellow, purple)

"Groovy!"

Yes :D

Ha, thanks :) 

edit - changed the title just for you 

Misleading title toht it wuz a N64 gaem goshhh. My favourite piece you've made thus far Eli.

I dig, a lot, very great work here, I have to add this to my favorites now :D

Added a crow, any better?

Welp, now I feel like a total idiot because it never even occured to me to put the crows on the lighter background where they could actually be seen x(

Thanks for the edit, it was a huge help! 

Really great work here, but it begs to have enemies on the screen

Well, that was fast :)

The pistol kinda seems to break the wide pixel limitation though! :)

(also, consider this ultra quick dirty imprecise edit I made: http://i.imgur.com/1O8iqS4.png )

I'm not sure how to change the gloves, given the tiny resolution :(

Added the pistol though, kind of. 

Nice Earthworm Jim for C=64

... but it looks like he has boxing gloves... and where is his laser pistol?

You win five internets. Brilliant work.

Added an improvised tire pile ;) Glad you like it!

And an Ocean loader :O Nice job!

Otherwise, I like it very much, immediately recognized both Jim and the fact that it's a demake mockup just by glancing at the preview image!
