Yeah.. while I agree with some peoples' criticisms, the "Completed" tag is on this topic for a reason. Besides, this is a free mod that people worked on in their spare time - some jank is expected. I was considering trying out the tools myself to mod in my old custom Tails animations I made, but I got busy with other stuff and never got around to it. Maybe eventually..
The point is, people need to learn to read.. Besides, is the platform section really that bad? I may have some bias, since I always played as Tails and his jump is insane compared to most of the other characters, but honestly I always found this game somewhat easy overall. Every enemy's attack can be anticipated and broken out of with the special ability, so really, the pitfalls were kinda the one thing that introduced some stakes at the end there.
