I like the concept!

I like the huge recoil on the matchlock pistol but the flash seems a bit too much.

 good point, ill be following your advice in future projects ;)

I really only see 12 colors. So, 64 is far too many. Pixelart always wants to have the least possible amount of clors.

well, you think its to much?

Where are these 64 colors???

 okay, i ll try!

 if you make a better muzzle flash it will be awesome!
