Neat! Music's awesome, too!
I had fun, but, I found myself often stopping to think, ok, which item will i switch to when I press this button?
And then I get hit by a crab.
It'd be nice if, for example,
pressing z switches to shovel,
x switches to pickax,
c switches to gun.
That way, I know for sure which button to press, and which item it will select.
Also, I'd accidentally waste my bullets cuz I'm so used to spamming the button to quickly mine or dig, lol.
