The intro was great but a little unfair since the little cactuspy was placed to close to where the character teleports, thus hitting him directly in the face! This stage definitely felt like the GB version of FireMan's stage with some unique enemies and challenging fire-block & flame-chute obstacles. And the beloved tile-block glitch was also put to very good use throughout this entire level.
The second was very reminiscent of the famous NES MM1 FireMan level, with the fire-jets in all the right places. I'm very pleased to see that I had the Ice Slasher in order to freeze some and use them as stepping stones to reach some power-items in high places. Some of the FireMan areas seemed a little more reminiscent of the MMPU version, rather than the original NES version. I loved the little backwards GB Fireman segment towards the end with the sniper-joes, flame-jets, and flame-chutes. That section was intense and a little difficult. I really liked how you used the constant fire-jets to simulate the flowing lava underneath some of the floors. Amazingly enough, there was absolutely no slowdown whatsoever throughout this entire, amazing & long Fireman remix!
