I may have found a bug? Like a real bug...
Tried running this on my Gameboy Color.
I am using the EZ Flash Jr ver: FW4 k1.04e. The game loaded fine etc but when it comes to play, holding Right on the d-pad causes the character to run at break neck speed, whereas holding Left he walks normally.
Tried the browser version to see if this was a 'feature' and its clearly not lol
So not sure if it's just happening on my flash cart (I tired a few other roms to be sure its not happening on other games and they play fine) or if this is a bug in the .gb file, but as I'm not a speed runner it makes the game basically impossible for me to play lol
Looks like a great little platformer none the less =)
