Well, apparently it's not crashing, so it's a relief already. And I just realized I didn't say here I released it.
I'm saying now then. I released Koopa yesterday.
I once said here I had made some changes to the psa I noticed could be useful. This is what I made:
-During the Neutral B charge, you can move Koopa around a little.
-You can choose how you want to move with the Neutral B, if grounded or with a small jump, depending of which button you press. If you jump, you may fall off ledges and the distance you travel is shorter.
-You have a minor degree of control during the Mortar Bill thing. It makes a bit easier to aim.
Also, some things that I should mention here for the sake of balancing.
Aerros mentioned two things that are true:
-Mortar Bill has a very long range. I didn't change it because it's a pretty powerful attack, but also hard to hit, and easy to self-destruct.
-Air Up-b may take too long to finish. But Koopa's jumps are not very good, what can force you to use this often. By using it, you will either be hit you end up into special fall, what will let you helpless for a good time.
Besides that, one more thing I find important:
-Koopa has even lower traction than Luigi. I made that on purpose to make something different, so that's a thing I'm not adjusting. I want it to be balanced with this feature included.
That's what I remember right now and are the things I'd like people to think about when playing with it. I'll post more if I find anything else more serious.
