Controls could use a bit of work
Too many buttons to take care of imho. Makes for a confusing/awkward play experiene imho.
Inventory should, maybe, be driven by the number keys.
Weapon range/hit detection is a bit too small, for some ennemies i can see a hit but it doesnt register.
Its annoying that some weapons have no effect watsoever on some ennemies, like katana on vampires doesnt even make them flinch. They just keep on doing their thing as if we were blowing air at them.
When we lose i cant seem to -not- choose to buy lives.
I just stop playing at that point. Good potential, good stuff in your game but im not finding it fun to play.
