I wanted to give some feedback on the demo, which I played quite a few times now.
The Good:
A.) Love the music, I enjoyed flipping through the songs on the sound test and that the music carried into the menus.
B.) Graphics look great. First stage looks pretty good, but stage 2 looks phenomenal.
The Suggestions:
A.) When killing guys, maybe there should be a bit more of a noise or a little flash or red blood spot or something? The character's attacks don't seem to have weight and killing someone doesn't give a feeling of satisfaction.
B.) I also suggest that the bosses flash or there is some indicator you are hitting them. First time I reached the boss I wasn't sure I was doing damage.
C.) Game speed is fast and sometimes it feels as though it is just a bit unfair when guys come out behind and get that quick hit. Maybe a tad slower would be better? I love fast games, like Summer Carnival on Famicom, but in that game enemies aren't coming from all sides.
Other:
A.) Game is hard! I wasn't able to make it past the second stage, so if the demo is indicative of the final release, maybe you should add a continue feature? The guys who are a lot better than me will go for 1CC anyway, the continue gives more people enjoyment and a chance to plow through.
B.) In the options menu there are two empty spaces you can click on. If these are placeholders for the final release, that's cool. If they are there in error, figured I would let you know.
3.) Will the game include a manual discussing game mechanics? I am not quite sure I am using the shield and power-up feature correctly and I am sure they are fine, but some guidance in a manual will be great.
