the main menu button don't really have enough contrast. light green text over aqua or yellow buttons just doesn't pop up enough, making them hard to read.
i like the samurai attack pattern, but right now they just basically land every hit against you. to avoid taking damage every single time you face one, they should have a chance to miss you imho.
i really like the idea of an arcade cabinet save station!
yeah i also noticed that there is no way to heal yourself, maybe enemy drops?
the boss at the end isn't very threatening at all, you can just shoot him from afar and he can't do anything about it
