just browse pixel joint a lot, sit and try to create your stuff :).
Best tool to create good pixel art? A good art background. If you know a little about drawing (color theory, perspective etc) the right pixels will come to you!
I would really love to have played this in the early 90s. Still fun, I just meant to say it as a compliment (like, well, you captured the vibe!)
Beautiful game, really enjoyed it :)
Very captivating piece of work :)
Very impressive composition. I'll keep a close eye on it, the weather thing is very nice :)
Very nice artwork style :)
