This was awesome !
I really like that you tried something not often seen when going retro, making a pre NES style olschool game, and you nailed it right down to the voice sample and the ending (which is really funny and has a cool and catchy tune btw) XD
Everything here feels authentic to the style you aimed for and the game itself is fun to play.
I think there's nothing more i could say as i didn't have any issues what so ever here
Congrats you did a great job :)
