You have to be somewhat persistent to get the download started sometimes. I can't read a whole lot of the runes, but it seems like that site (like a few English ones) won't allow you to download if the server's too busy. Usually if you repeatedly refresh the link from the first post and click the button it'll let you in after a few tries. Just be stubborn about it. You know you've gotten through when you see the English 'click here to start download' link.
As far as the game goes, I have to agree. I rather like this one, and am eagerly awaiting updates. Metroidvania games are right up my alley. This one is more.. The gameplay and (almost) the difficulty of a NES Castlevania with the smooth controls and character movements of a modern DS-vania. It doesn't have the itemhunting, Metroid- part of the Metroidvania. But still, I approve.
For those of you having issues with axes, if you hit them from the right angle they should fly right back at the enemy that threw them. If you didn't get it right, you can still hit the projectile a second time while it's falling back down at you and it's usually easier to aim it then. Axedoods die in a single hit from their own weapon, so it's a great tactic if you can pull it off.
