Dear Paul, in short words - i'd pay you 5€ for a extended REU-Version, with all missing features... .
Very good work by the way. I am not completely sure whats causing it, here and there it seems the sprite-multiplexer has a problem somehow / when screen is full of action or I carry something, here and there a sprite is flashing up on positions, where it shouldn't (using v1.3)...but it did not affected gameplay, which is very cool in my opinion. Even though I did not managed until now to get past second world...
