1xFish on a stick! Used the same colors as the original for simplicity - I'll choose a better palette later.
To the left are some carrots, since I couldn't get the fish looking good in such a small sprite.
To the right of that are three ideas for logos.
- The official English logo downsized.
- A logo in Japanese
- A logo modeled after the Dig Dug original. The "Hara" and "Kawa" can be swapped, in case someone is more likely to read it as "Umikawa Harase"
They're hastily made, all of them, so tell me which idea you like the most and I'll spruce up that one and make a proper logo out of it.
I was thinking the ground would be better served copying the floating geometry patterns of the early games, since shoveling through water would be a bit heh
My concern with a checkered tiles is that it might be hard to see enemies within all the detail checkers would bring. But I'm sure I could make something work.
I actually came across this screenshot from the Sharp X1 version of Dig Dug:

Great palette for a sea-themed game! And it's perfect that it's from the Sharp version, considering Kiyoshi Sakai had a fondness for developing games on Sharp computers.

So maybe rather than water, it could simply be blue soil like this? Or maybe some kind of blue marble...
I was also thinking I could replace Kawase's shoveling sprites with swimming/waddling sprites... That could be fun!
I'll do the score items next, and then whatever logo you think would be the best fit for the hack.
