Maaan, finally an oportunity to roast your ass!
Just kidding, your tutorials are quick and on point, there's nothing not to like, not even the fact you're basically mixing the aesthetics of Edmund McMillen and Tomorrow Corp ;P
(I know developing your own style is hard)
This is a very nice game, pleasant to look at and to hear. Unfortunately it has a major design flaw - the second character seemed more like a setback than an oportunity. I just rightclicked and moved him a bit away from the bullets then got back to the "main character", this was my strategy most of the time. Wish there was also a WASD control scheme. Still, you get many points for the brave concept alone, and also I've seen your summary video, feels bad man. I can relate - I too came for the fame and fortune of Mark's video, and I too didn't do as well as I could.
Great job man, keep doing stuff. Would love to see you do a bigger game someday :)
