I'm not a marketer, but I play one on television, so...
If these guys want to sell more copies, then I suggest they make a better video for their game's website. Here's what I got from the video:
- Dull, repetitive level design.
- Only three weapon types shown, bomb, sword, and fireball, of which only sword and fireball are used.
- Only three enemy types shown.
- Underwhelming enemy AI. These enemies look like a bore and a grind, rather than a challenge.
- Over-the-top damage blur effects used so often that they do not heighten tension, they just make it hard to see.
I realize that this is an alpha and it's not finished yet. I realize also that you can't edit together the "best hits" and still call it a gameplay video. But you definitely should have prominently showcased a trailer instead, and put the gameplay video on another page. As it is now, the video doesn't make the game look very good. I got bored before the video was over, and the video isn't even that long.
