I put this on a flash cart and played it over lunch for a few minutes on my model 2 Genesis. I only reached level 2 (I'm bad at video games) but as far as I can tell it works perfectly.

BTW I love the look and feel of this game. It's very fun. Thank you for sharing it :)

Thank you for playing, for informing me and for your kind words. 

You are the first reaction over my game and you made my day.

And yes it is quite hard. I tried to make it as hard as  the old games.
