Um... I think the bosses are too easy actually, if there is a sequel can you make gameplay more difficult please? :D Y'know, shooting patterns were too easy to figure out and dodge, and not enough variety imho. :/
There seems to be a lot of these types of games coming out (like The Company of Myself). Controls were a real annoyance for me in this game, mid-air control was awkward and caused many accidental deaths. The message didn't seem to be communicated quite as well as some other similar titles (probably just me) but it was still done very well.
