The zip file are the sprite-sheets I doodled for use in https://clyde.itch.io/sprite-walls
You can do anything you want to with them. No attribution is necessary, but it's fine if that's what you want to do. Really, I just thought it might be fun to have these sheets so you can see what the environments are made out of and identify the parts inside the whole.

I plan to doodle more sheets and make more rooms and update the game. So hopefully it will change. You may not be able to access an old room and if you tell someone that there is or is not something in the game (though you may have been corrrrect at one point) they may prove you wrong.

A bunch of colourful sprites that were rejected by various videogame projects have banded together to star in their own game, which they've called "Nitty Gritty". Time to fire up that minigun, Nitty!

Z or Space - let 'er rip
Arrows - slip and weave

There are 17 opponent sprites. If one of them slips past the bottom of the screen, it may evolve into a new form and reappear later in the game. Exactly 8 of them are capable of evolving... some of them more than once.

After the game ends, you see a roll call of all the soundly defeated sprites.

EDIT: Updated Oct. 2011 with a title screen, music, and save files.

Made in Game Maker... I know, blasphemy.
