-The henshin is way too dang long, and I'm a tokubro.
-Good lord that fall speed is intense. Might want to loosen it up a bit.
-I really hate dash on Circle. I always L dash in megaman, it's optimal. Needs controller mapping.
-Form changes don't make much sense and don't follow a coherent pattern. None of them feel like the same person.
-Dark gun form feels like an inverse Battride War Kuuga Pegasus or perhaps Den-O Gun Form. I don't think it translates well in 2D but it feels fairly spot in to that.
-Did you really need two gun forms?
-Something feels a little off about moving. I think it's a lack of velocity. It'd probably feel better if it took a few frames to reach max speed.
-Finish overlaps on the pause menu.
-You have areas with obvious ladders but you can't climb them. It makes you want to climb them but you can't.
-The boss couldn't do a damn thing to me in the default form lol.
-A lot of the background seems like an incoherent mess. I was never too sure what I was looking at, and the further you go, the more it seems to just be random chaos.
Overall, not a bad demo. I could see things getting worked out to be pretty good! Keep up the good progress!
