for this, and it sums up all of my thoughts of this hack. It's just a basic level hack.
I expected newly arranged levels, but this hack only added pits after pits after pits from the original levels; Airman fight with pit falls! (well, that added a good challenge)
About that Flashman stage, I prefer Robot Master stages complete-able even without the Items in hand; Heatman stage requires you to have Item-3 if you're not a good edge-jumper. And the creator missed a few background graphic displacements.
