Thank You
An excellent overall game, played it right to the end. I really enjoy smooth games like these with actual CONTROL. Many other Flash games I've played had horrid control, but this one, keeping to Megaman tradition, had responsive, non-jerky controls. THIS is more like how Flash platform games should be done. The Final Boss was beaten in no time once I found a strategy to defeat him, putting to use an Archille's heel you mentioned yourself. I will say nothing more.
One interesting, minor bug I noted that may have already been mentioned: when you take out a shooting enemy (such as the venus flytraps in the forest area), any propellants flying toward you are also destroyed.
