It's not an SMS emulator, I chose the letter O as it was in the middle of WASD and arrow keys so both types of movement scheme could use letter O key easily.
In hindsight a simpler option like spacebar would've been better.
Oh? It's not a SMS emulator? It looks like a SMS game, unless this is a Godot game running in HTML5. If so that's cool, but I would love to see this as a SMS ROM.
Oh awesome! I can't wait! I'll be honest and say that when I first saw this I thought it was a SMS ROM. No wonder there isn't a download button yet! lol!
