Is there an actual .rom I can download? I'm familiar with the pico8, but I have never tried it before. Somebody a while back made a pico8 emulator for the Saturn, so that would be an interesting way to play this game :D
my primary criticism would be the fire rate of the weapon is pretty low, I could do it but, it felt like a losing battle.
the other is for keyboard controls, I would just use WSAD for direction and maybe space for fire or some other keys, it worked but it wasn't a pattern I'm used to.
I didn't see a way to change the weapon, I suppose I could have pressed every key on my keyboard, but by then I was already dead :D
