some of these might sound like nitpicking so no stress :-)
also I am not aware of any official bug tracker so maybe double posting...
1. missing feet
2. if you die near this "double hill" after resurrection there is the gap between the hills. Same can happen also at the beginning of the level 4
3. lizards are missing feet and looks a bit too low
also few more:
the rope is not acting as in the original, stretching is different
the rope is starting not low enough, there is gap
the rope show up only after the player reach the spot, in the original, rope is there all the time.
i expected I should press jump to get off the rope not right and it is working only in some limited area, simply it is weird.
4. i died several times on the rope and somehow the bat gets completely off to the left
5. Actually I am not sure how the original game plays but in your port if you die and get resurrected, the "hard" part is over. For example I never killed the rhino. He always killed me and after resurrection the rhino was done. I think for better gameplay, player should resurrect like one screen back and have another try on the mob...
great job anyway
