I have a dark green which I use on the pipe, but I didn't use it on the trees even though I could. I think my rationalization was to keep things flat if possible. The pipe really begs for some roundness though, so I broke two rules, highlight and slight dither and shadow. Uh, three.
I tried to keep it flat and undithered as far as I could though. And some of the shells have speculars so I didn't really break that rule too much.
I tried softening the speculars, but it looked like... the star skies I tried to pixel on my Amiga back in the day.
Top left guys are Snapjaw and a plain bird from DK.Jr. Yellow bot is from the Nintendo Power comic based on SML.
I played a lot of Game & Watch games as a kid. It's why I included the Snapjaws. The arcade and NES version of DK.Jr. is pretty cute too.
http://www.spriters-resource.com/gameboy/gnwgal3/sheet/8965I wasn't too impressed by the Game & Watch ports to be honest. And the Snapjaws in Mario vs DK looked very bad.
http://www.mariowiki.com/SnapjawI thought about punching up the
http://en.wikipedia.org/wiki/Chiaroscuro effect (make some of the lines into more defined shadows), but decided against it (I don't want a Mignola look). I'm doing it mildly here and there though.
I still can't see the tree-man
I don't know how I used the statue power. I guess it could be fun to use if Mario kept is momentum. Maybe turned into a stone ball which could crash blocks, enemies etc. Like a wrecking ball.
Animations: I was thinking of giving each character the same set of animations, whether they use them or not. They can be blank frames, copied, or whatever. It's easier layout the sheets and code stuff this way. Having the engine alternating two idle frames for example is good if you feel like adding a simple animation later.
Stand idle 2
Duck idle 2
Walk 4
Run 4
Slide 2 (turn/skid when attempting to move in opposite direction of movement)
Duck slide 2
Jump up 2
Hit top of head/hand 1 ? (brief overriding strain frame)
Fall down 2
Hard landing 1 ? (brief overriding strain frame)
Throw 2
Float idle 2
Swim 4
Wall idle/hug 2
Wall climb 4
Wall kickoff 1 ? (not sure if a transition to the regular jump frame is needed)
Take hit 2 (pain / flash, Megaman style ? Alternatively, Mario could emit shock particle without being interrupted.)
Die 2
Crushed 2
(flipped frames excluded, engine does that)
Ingame editor with a BG and FG layer. Mario is the little dots. Edit: Oh, it's 16px based for now. My 8px alignments are artificial. This is a quick test with just 16+16 block types.
