For those of you that noticed that the 20th version is slower then the 15th version I just figured out why and I wish I did before I already finished it lol.

Anyway the games speed is tied to it's difficulty, that's why the game is slower. It's slower again on easy and at full speed on hard. As well as other little changers here and there such as some enemies not activating their shields.

Anyway way so yeah just set the game to hard to play it as intended at full speed and all.
