Not bad for level designs. However, on Woodman Stage the background colors need to be of different palette, its hard to tell which are the solid platforms from the background. I found a bug on the ladder going upwards. If you jump-climb the ladder off screen, Rockman would stand below the next screen, moving him would drop him back down.
In Heatman Stage, there's a bug on the midway checkpoint, Rockman would appear below the platform in the middle. Jumping out of it would free him. As for the level design, I think this stage would be Metal Blade dependent, you won't survive without it. I would suggest tone down the use of Tellies.
2 stages are complete (with the exception of the bosses).
Does that mean you'll gonna hack the bosses' AIs? If so, make some new robot masters
