Wow

Okay these right here well they are pretty neat and interesting. I do think they need a bit more details in a background, but as they are sprites you are showcasing to use, I understand why you stuck with the black background as that will make it easier to transfer over if any users wish to use them in their game. I think the detail and expressions in each character of PICO is nice and I would hope you'd still finish your game. There is always time, even if a short version where you toss him and see how far he goes, you know, something basic, it would always be a good addition and interesting to view. Don't give up on things you start, because I am liking what I see so far.

~~THINGS TO IMPROVE ON~~
You should make this into that game you wanted to make

~X~

Well done! Try to add more visuall effects (partices for example) on attacking animation next time to make quick movements smoother.

This looks pretty cool, I've seen only few pixel drawings here and for a while I had the urge to try to make one as well, but then didn't...:D I really like this fella tho, his expression when he attacks :D AND especially how his eyes light up with red in attack 2! That's a nice detail, loving it :)

this is really cool, cyberdevil! hope that game comes out soon!

I love how he goes super sayian when he double jumps! lol nice
