These are some very nice isometric sprites! great colors and poses!

I love the color choices. I want to play.

iiiiiiiiiiiiiiiihh you have hit my hearth...5/5

WOW, it's awesome atmosphere!!! I like see real game... Not mockup... :P FAV 5/5

@DeProgrammer: It seems he's more oriented to the comic versions of the turtles, where they all had red headbands :P

Nice atmosphere overall...it just seems to lack a HUD, but it could be a hud-less game :D

I love it all around. No complaints (except the one with swords needs a blue headband, and the one with sais needs red. )

Characters are nice. I like environment too ... maybe need more work on enviropment like that light brown boards on the door, some  differences in the bricks ets. ...  I think that light grey for the plaster between bricks and wall is very contrast and need to put with more accuracy !

Cheers and I'll wait your next work :)

Wow, very awesome.

I like this! The details are great, especially the grungieness of the sewers. I have one suggestion/requst.... Give Splinter a tail! (I hate how all the modern TMNT cartoons make him look like a wolf instead of a rat...)

You could make a real mockup, with no assets in the composition. I saw the preview and was excited to see a nice mockup. Anyway, it's still a great work ;D

BTW, gotta love the TMNT.

Very nice!  Keep up the good work!
