Hucast never gave me the 10% Kickstarter bonus to begin with. I preordered Ghost Blade Supporter version and it didn't apply. They never responded to my inquiry until I wanted to cancel my order outright after they announced a larger run. Still no warranted discount though.
More on topic: this game looks cool; a definite throwback. I want to get the limited edition, but even with the soundtrack the price seems high to me. Plus it's not like Hucast ever runs out of inventory of their developed/published games. Despite the "only 300 ever" I bet it'll be available after launch, and eventually on sale.
